Installation and configuration

Installing EDuke32

1. Copy the contents of the DN3DINST or ATOMINST directory off of your Duke Nukem 3D or Duke Nukem 3D: Atomic Edition CD to a directory of your choosing on your hard disk.
2. Download the latest version of EDuke32 (currently a development snapshot) and start the installer. Note: if you downloaded the zip version of EDuke32 instead, extract it to the directory you created in step 1 and proceed to step 8.
3. Click next to view the terms of the GNU General Public License. If you agree to the licensing terms, click "I Agree" and continue to the component selection screen.
4. Choose which components you'd like to install. The default selection is to install both EDuke32 and Mapster32, the enhanced Build editor. If you're just here to kick ass and have no plans to create custom maps, feel free to uncheck the 'Level editor' checkbox. If you plan to play multiplayer using version 1.5.x of DukesterX, make sure to select that component here. You may also want to install the sample custom content definition files if you plan on modifying the game further than creating basic user maps.
5. Click 'Browse' and select the directory you created in step 1. Click next.
6. Select a start menu folder in which to place the EDuke32 shortcuts and then click 'Install'.
7. Once you click the 'Finish' button, a list of changes detailing the new features and bug fixes since the previous version of EDuke32 will be displayed. Feel free to close this if you aren't modding the game.
8. Run EDuke32!

Configuration menus

Game setup

Crosshair

The crosshair option allows you to configure whether or not you want the in-game crosshair to be displayed. Available settings are off, on (100%), on (50%), and on (25%).

Mouse setup

Under mouse setup, you will find the menu which allows you to configure which functions are assigned to which mouse buttons. You will also find the following options:

Sensitivity

Sensitivity is a slider which allows you to configure how sensitive the in-game mouse movement is. Lower values equal a lower degree of mouse sensitivity, of course.

Mouse aiming toggle

Mouse aiming toggle determines whether the mouse aim functionality in the game is toggled on or off. Note that this option will be disabled if the 'mouse aiming type' option in player setup is set to 'held'. Available values are on and off.

Invert mouse aim

Invert mouse aim controls whether or not vertical mouse input is inverted in the game. If this option is enabled, moving the mouse upwards in-game will move your view downwards and vice-versa. Available values are on and off.

Advanced

X-axis scale

X-axis scale is a multiplier for mouse input on the X axis. This can be used to fine-tune the horizontal mouse sensitivity separately from the vertical mouse sensitivity. Values range from -4.00 to 3.88.

Y-axis scale

Y-axis scale is a multiplier for mouse input on the Y axis. This can be used to fine-tune the vertical mouse sensitivity separately from the horizontal mouse sensitivity. Values range from -4.00 to 3.88.

Dead zone

The dead zone option allows you to configure the game to ignore a certain amount of mouse input. This can be useful if you have a mouse which "twitches" and the subsequent sporadic twitching of the game view bothers you.

Digital axes actions

Digital axes actions enables you to assign game functions to the so-called 'digital axes' of your mouse. Most players will never have a need to change this.
