Change current Editing Mode (Tile / Objects / Paths). The current mode is writen on the bottom / right corner.

	Editing Tiles		Editing Objects
	Editing Paths

Toggle Floor layers 1 and 2 :

	F1 and F2 activate		F1 disable
	F2 disable		Both F1 and F2 disable

Toggle Object infos layer. 4 modes : none, "Type,Id", Animation Speed, Name in Obj.txt :

None	Type,ID	Animation Speed	Name in Obj.txt

Toggle wall layers. Like for the Floor layers, you can toggle all wall layers. F5 is for the Wall layer 1, F6 for the Wall layer 2, and so on :

	With the Wall layer 3 activate		With the Wall layer 3 disable

Toggle Special Tiles drawing priority. 2 modes : draw like walls, or draw on top of all gfx (like roofs). It allows to see Special Tiles hidden by Walls. On the 2 precedent images you can see that the upper Green Special Tile is only visible when the Wall layer 3 is disable. That's because for this screenshots the Special Tiles drawing priority was set to draw Special Tiles * like walls *, thus the upper Green tiles was hidden. Now, let's hit the F9 key and here's what we have :

	Special Tiles draw like Walls		Special Tiles draw like Roofs

Toggle npc's paths layer (not yet editable). The NPC in the game will only use the points on the Pink lines (and randomly), and they'll never go back to their original starting position.

	Lots of NPC paths in Lut Gholein		NPC paths hidden

Toggle the Shadow Layer. There are 4 Shadow modes : Disable, "As-is" (solid, original colors), White (all pixels are replace by White pixels), and Transparent (this is the default value). In the game you have the choice between 2 quality for the Shadows, in the editor their correspondances are the "As-is" and the Translucent modes.

	Disable		"As-is"
	White, that way it's far easier to see them in some case, like when there's no Floor layer		Translucent

Toggle walkable info layer, 3 states : disable (default), simple infos (walkable & jump infos only), complete infos. In this state a little help window appear at the bottom / right corner (it's toggleable by the T key).

	No walkable infos		Simple walkable infos
	Complete walkable infos, help window activate		Complete walkable infos, help window disable

G

Shift + G

Toggle the Tile Grid state between the 3 available : disabled, over floors but under walls, and over floors and walls. If the Shift key is pressed it do the same but in reverse order.

	Tile Grid disabled		Tile Grid over floors, but under walls
	Tile Grid over floors and walls

View only this layer. It's an easy way to check which tiles are on which layers : Press Shift, then press F1 to see what are the Tiles of the Floor layer 1, keep Shift press and type F2 and you're now viewing only the Tiles of the Floor layer 2, and so on.

It's especially usefull if you want to select some Walls but without Floors that are below for instance : press Shift and hit the F5 key, and you're now able to select only the tiles that are on the wall layer 1, without the floors.

That's the reverse of the precedent command : it will make all layers visible, except the one you have the key on.

The Shift + ... and the Ctrl + ... commands are shortcuts, since you can achieve the same results by pressing where needed the keys F1, F2, F5, F6, F7, F8 and / or F11. But it's more simple and quicker that way.

Reset all layers states to their default value. So if you're lost in knowing what layers are disable, just press this key and all Floor / Walls / Shadow layers will become visible again.

I'm usually using it that way : Shift + ... to view only 1 layer, then I select the tiles I want on that layer, then I press Backspace to view back all layers.

0 ~ 9 are the keys that are in the upper part of your keyboard, not in the keypad.

When more than 10 DS1 are loaded (via a .ini) the editor split them into 10 different SETS, from SET 1 (CTRL + 1) to SET 10 (CTRL + 0). In each SET you have the usual 10 slots of DS1. SET 1 contain DS1 #1 to #10, SET 2 contains DS1 #11 to #20 ... up to SET 10 that contains DS1 #91 to #100.

For instance, to copy tiles from DS1 #22 to DS1 #84 you'll do :

• CTRL + 3 (enter SET 3, it contains DS1 #21 to #30)
• 2 (activate DS1 2 of SET 3, so it's DS1 index : 10*(3-1)+2 = 20 + 2 = 22)
• select your tiles and copy them (CTRL + C)
• CTRL + 9 (enter SET 9, it contains DS1 #81 to #90)
• 4 (activate DS1 4 of SET 9, so it's DS1 index : 10*(9-1)+4 = 80 + 4 = 84)
• place your tiles

Note : when more than 10 DS1 are loaded, the menu bar contains 2 rows, as an
additional row appear to help you to navigate through the different DS1s. This 2nd row display the current SET (group) of DS1, the current DS1 index that you are on, and the full path of this DS1.

When is it usefull to load that many DS1 ? Well, a maze of an area is composed of usually 72 DS1, so this is the time to use this functionallity. Onyx used 84 DS1 for his replacment of the Act 3 dungeon ;)

Up, Down, Left, Right

Mouse on the borders of the screen

You can scroll the main editing window by pressing the arrow keys. And you can also place your mouse exactly on the 4 sides of the screen to achieve almost the same result.

The scrolling speed when using the arrow keys is in the ds1edit.ini, as long as the scrolling speed when using the mouse. If your computer is too old / too powerfull, or simply if you don't like the default scrolling speeds, adjust these values in the .ini to fit your needs.

+, - (keypad)

-, =

Mouse wheel

Hit the + and - keys to zoom in or out. You can only use the internal zooms (which are powers of 2) : 1:1, 1:2, 1:4, 1:8 and 1:16. You can use both the keys on the keypad, and / or the keys between the keys 0 and the Backspace. With these keys, the zoom is always done on the Tile / Sub-Tile which is at the center of the screen.

You can also use the Mouse Wheel for zooming : roll it forward and you're zooming IN, roll it backward and you're zooming OUT.

C

Mouse
button 3

Center the map to the Tile (or the Sub-Tile) the mouse is pointing. It also automatically set the zoom to the value defined in ds1edit.ini right after (check the line center_zoom in that .ini)

You can also use the Mouse button 3, which should be the Roller while you're pressing - not rolling - it. Press the Mouse Roller, then roll it either forward or backward, and you're zooming and centering the map to the Tile / Sub-Tile the mouse is on.

P

Shift + P

Printscreen (makes a screenshot). They're .pcx, and have names like "screenshot-00037.pcx". They're created into the directory of the editor. The editor will never erased a previous screenshot, it'll always search for the next unused number.

If the Shift key is pressed, it'll make a BIG screenshot, and you'll have the entire map in 1 image. Note that this big screenshot takes care of the current zoom and various graphical layer state. In addition, the format of this screenshot is in .BMP instead of .PCX, because of the .PCX image dimensions limitations.

Maintain the Left Mouse button pressed, and you're now selecting an area of Tiles : move the mouse around and you'll change the Tiles that will be selected.

When you're releasing the mouse button, different actions can be made, depending of the key that is pressed :

The selection is based on what you're seeing. By changing the Layer's state (using the keys F1, F2, F5, F6, F7, F8, F11), you can select / deselect a Floor, a Wall, a Shadow, multiple Floors / Walls / Shadows, etc...

Tip : you can press the left button, then toggle your layers, then make your area selection just like you want, then toggle the layers visibility, press an action key to make a command (Shift, Ctrl or H) and released the left button only at the end. Most of the command still work while selecting an area.

Hidding Tiles is safe. They're not deleted from the map, this is just a temporay state : press the S key (like 'S'how), and all the hidding tiles of the map will be visible again. Hidding Tiles is usefull to see what are the other Tiles that are behind. Note that even if they're hidden, they can still be selected / deselected when making an area : the selection process of the Tiles is based on the global Layer visibility only, not the Hidden state of individual Tiles.

Let's exercise a little :

	We already have a selection composed of 2 parts (the blue Tiles), and are now selecting a new area (the orange Tiles)		If when releasing the Left mouse button no key is pressed, then the area will become a New selection
	Let's come back in past and let's press the Shift key instead of having no key when releasing the Left mouse button : we're adding the area to the existing selection		Now, let's delete from the selection the Floor Tiles that are under the vehicle. Press Shift + F1 to only see the Floor layer 1. Then makes an area that includes that Tiles...
	... and press Ctrl before releasing the Left mouse button : you have excluded the current Tiles of that area from the selection (but only the ones on the Floor layer 1, since only this layer was visible)		Now, press Shift + F5 to only see the Wall layer 1. Then select a new Tile of that layer, press Shift, release the Left mouse button and...
	...and you have added a new Wall (but not the Floor) to the selection. Press Backspace to view all layers : you can see that the vehicle don't have its Floor tiles selected, since we have excluded them from the selection just before.		Now let's try to Hide some Tiles. Make this area but keep the Left mouse button pressed for now.
	Now, press Shift + F5 to see only the Wall layer 1. What ? Yes, keep the Left mouse button pressed. Yes you can. As for me, I can press the Right Shift + F1 while using only my Left hand.		Now, press the H button and release the Left mouse button : you have Hide some Tiles. But since only the Wall layer 1 was visible, the * Floor * Tiles were not hiden.
	As a proof, just hit the Backspace key, to make all layers visible again : only the Tiles on the Wall layer 1 of your last area are hidden, not the Floor Tiles.		Now, just press the S key, and the hidden Tiles are visible again : they were not deleted from the map.

To be honest, the possibility to change the Layers visibilty while making an area was not done on purpose, it's a side effect that you can use, but I don't think someone will really need it. It can be usefull in some cases, but not often. So just remember these important points :

• Selecting Tiles : press the Left mouse button, make your area, press a command Key (if needed), and release the button.
  
  
• At any moment, if you're lost in your layers visibility and or / hidden Tiles, press Backspace then S : all Tiles are now visible again.

A powerfull command : select all Identical tiles in the map, as the ones you're clicking the mouse onto.

Choose a Floor, press the I key and maintened it pressed, click on the floor, and all the same floors on the whole map are selected (even if they're on another layers). This can work even if there are several tiles on the cell, in that case you'll have a selection composed of several type of tiles.

Another usefull thing is that you can still use the Shift and Ctrl key to respectively add all these tiles to the current selection, or delete them all from the selection : choose a cell which have only 1 floor, select all the same floors with the I key. Now, choose another floor, but press Shift + I : you'll have in your large selection 2 type of Floors now. Press Ctrl + I and click on one floor of the selection, and you'll have only 1 type of floor in the selection.

The Tiles types that will be searched are based on the visibility of the layers, but the search (in the whole map) to select them is done disregarding the Layer visibility, and even on hidden tiles.

This command is also usefull to have an idea about the density of some tiles in the map. Tip : you can keep the I key pressed while moving the mouse on different Tiles... you'll make new selection each time very quickly, thus you'll be able to analyse their density very quickly.

But let's make some exercises, to help you clarify how this command is working :

	Let's say that we already have a selection. Now, go on another Floor Tile, press the I key, maintained it pressed, and now click on the Left mouse button...		... you obtain a New selection, composed of all the Floor Tiles on this map that are exactly the same as the one you requested.
	Now press Shift + F5 to view only the Wall layer 1. Then go on a Tile of this layer...		... press Shift + I and click on the Left mouse button : you have added all the Tiles on the map of that Type to your previous selection...
	... but since only the Wall layer 1 was visible, you only added the Wall Tile, not the Floor Tile that was under, as an hit on the Backspace key will confirm you. Now, go on a Floor Tile of the selection...		... press Ctrl + I, and click on the Left mouse button : you have removed all the Floor Tiles of that type from the selection.
	Now let's go elsewhere, exactly here, where there are 3 Tiles in that cell : a Floor on the f1 layer, a Stone Wall on the w1 layer, and the Left part of a Tree on the w2 layer. Press I and click on the left mouse button...		... you have made a New selection, composed of 3 different types of Tiles, because there were 3 kind of Tiles on your cell, and all 3 were visible when you asked to select the Identical Tiles.
	Now, press Shift + F5 to view only the Wall layer 1, go on the Middle part of the Tree, press Shift + I and click on the Left mouse button...		... you have added all the middle part of this Tree to the selection, on the whole map. Add again the Right part of the Tree (Shift + I on the Tile of the Right part) ...
	... press Backspace to view all layers, and check at the opposite of the map : as expected you have added all the identical Trees of that map to your selection, and only the Tree, not its Floor Tile.

For instance, say that you are editing the map duriel.ds1 for the first time. When you'll ask to save it, it'll rename duriel.ds1 to duriel-000.ds1 and save the current state of the map into the file duriel.ds1.

Next time you'll make a save, it'll rename duriel.ds1 to duriel-001.ds1 and save the current state of the map into the file duriel.ds1.

So, the duriel-000.ds1 is always you original .ds1, and the next numbers are the following versions. Your last version is always the duriel.ds1, without the numbers in the name. Numbers are for backups.

Undo the precedent Tiles modifications, up to the very start. Note that when you make some multiple undo and then start to make new modifications, the undo buffers are reseted : the ones you have just used to get back to the current state of the map are lost. Also you can't undo an undo : there's only 1 way of undo.

The editor is using its directory data\tmp to store temporary files. They're small and are deleted when you're exiting the editor.

Use a Night preview. 2 modes : lowest quality, better quality. This is just a toy for now, as it don't support any ambient light level / light radius modifications, but it can help you to figure how a map will look in Dark Areas (llike Caves, Crypts, or simply an outdoor area at Night time).

While in Tile / Object / Path mode, press N and you're in the Night preview lowest quality (Night 1). Press again N and this time you're in the better quality (Night 2). To exit one of the 2 Night preview modes, presse Tab, or press N until you go back to the original editing mode.

	In an editing mode		Press N and you're in the Night preview mode, lowest quality
	Press N again and you're in the Night preview mode, better quality

If you try to copy / paste some tiles from a ds1 to another, you can expect big distorsions. If you want to avoid them, only copy / paste between ds1 that have the exact same ID (in data\global\excel\lvlTypes.txt), and the exact same DEF (in data\global\excel\lvlPrest.txt). This is the way the game use tiles that make difficult the use of certain tiles in another .DS1.

	First, select this Tent. Then press Ctrl + C ...		... and a preview of the selection appear, following your mouse movments. If we place the Tent here, some Tiles will be deleted, as the Red Tiles are indicating
	But here it'll be fine, since all Tiles are Green. Let's click the Left mouse button		The result after the copy/paste

DEL (keyboard)
DEL (keypad)

Select some tiles, even in different layers, then press DEL to delete them.

After a Copy, a Deletion or a modification of the Selection, if you want to cancel your actions and come to a precedent state, don't forget to use the Ctrl + U (Undo) feature.

As an exercice that combine both Copy and Deletion, let's increase the size of the Baal Throne Room :

	Select this border		Press Ctrl + C to copy it, then place the preview here
	Click on the Left mouse button to drop the preview in place		Now reselect the previous border
	And press DEL to delete it		Select these 2 "lines" of Tiles
	Ctrl + C to copy it a first time here		Immediatly after having drop the preview, press again Ctrl + C to copy it a second time here
	Press Ctrl + C again for a last copy here		That's done, you now have a bigger Throne Room. Of course it's far from perfect, just check the Walls on the upper/right border : they're not making a good sequence of Tiles.

Sometimes you may see some Tiles with numbers in there, at zoom 1:1. That's the way the editor show you that there ARE Tiles somewhere, but they have a Flag that make them invisible in the game. That's also to allow you to select them.

It can be some Tiles that are on each side of a River, or tiles to block your way like in Haroggath. But you can also see them on almost ALL maps of the game, at the far Top and Bottom corner, like in the screenshot below. I strongly recommand to leave these last ones in the map, as it seems they're used by the game.

	Invisible Tiles near a River		Invisible Tiles on each side of a Map

"Weird" Tiles are mostly unknown in fact, so don't play with them.

Advanced tile editing. Warning : NO UNDO IS POSSIBLE !

There are 2 possible windows. It depends if you have a selection of tiles (even just 1 tile of 1 layer) or not. In the case there's a selection, the possible bits to edit are restricted to the tiles inside that selection.

• When there's no tile selected at all, in the Tile Editing mode, press the Ctrl and the Shift key, then click on the Right mouse button, and this window appear :

Here you can change all the internal datas of the Tiles, even some unknown. Usually you'll only edit the Hidden or the Unwalkable bits for a particular Tile.

For instance in the screenshot, if the Vis special tile on the W1 layer has the Hidden bit set, this is because this warp is not part of the Vis special tile, and therefore the Vis has no graphics, at all. In order to don't see a Green Tile in the game, we tell the game this tile is invisible.

If you set the Unwalkable bit to 1, then the entire Tile becomes unwalkable, This is usefull to makes floor unwalkable without having to play with DT1 walkable infos.
 

• When there's a selection, the window that will appear is globaly the same, but there are more colors.

  0 or 1 indicates that all tiles are using the same bit value.

  0 or 1 indicates that some tiles are using a 0, others a 1. If you don't edit this kind of bit, the tiles keep their original values. If you edit it, all tiles will use your new values (and the bit will no longer be blue but white as well).

  - indicates that this bit is not editable, since no tile in the selection is on this layer

  Let's say that we want to make several tiles unwalkable at once :

	Select the 3 groups of tiles, then press the Space key to see the walkable infos. Here these 3 groups are walkable for now. Now, press the Ctrl and the Shift key, then click on the Right mouse button...		...and this new window appear. Set the Walkable bit to 1 for the F1 layer, and click on the OK button (or press the Enter key).
	This has set all the tiles on the F1 layer of the selection to have the bit Walkable set to 1, so all the 3 groups are now unwalkable.

The paths editing is still very basic, but with patience it's posible to do what you want.

In short : you select 1 and only 1 object in the Object Editing mode. It can be either a Type 1 or a Type 2 object, but only Type 1 (Monster / NPC) objects can use paths in the game. You then click on the ALL NEW button to delete the current paths and create new ones, by clicking on the map. To change the (hardcoded) "Action" (animation and / or sound) that the NPC will do at a particular place, click on the (Enter) SET ACTION button and type a number in the keypad, then press the Enter key and the next paths that you'll place will use that new Action value. When you have finished, click on the OK button, and the NPC have now whole new Paths.

	Select 1 and only 1 object in the Object Editing mode (either the Label or the Feet of the object will work), then press TAB to go into the Path editing mode.		You can still use the usual layer toggle and Space key if you want. Click on the ADD NEW button and now click some times on the ground, this create new paths.
	Click on the (Enter) SET ACTION button, this open a window where you type a number that will be used as the default values for the next paths to adds. Press Enter to close the window.		Continue to click on the ground : as you see the new paths are using that new Action default value.
	Continue to adds paths and to change the Action values, until you consider that you have finished to add new paths.		At any moment, if you're not satisfy with your changes, click on the CANCEL button to restore the original NPC paths. If it's good for you, click on the OK button, it saves your paths editing and assign them to the NPC.
