Changing keyboard up/down/left/right buttons to w/s/a/d in Spectator Mode

Hi,

First of all thanks for the great framework.

I am wondering whether it is possible to change the assignment of keys up/down/left/right to w/s/a/d in spectator mode ? Thanks.

I think you can do this by simply changing the settings when you launch a vizdoom game, and the changes will persist (haven't checked).

You can also add game arguments to bind the buttons you want. If game is a DoomGame instance in Python, then this will map u/d/l/r to WASD:
game.add_game_args('+"bind w +forward" +"bind s +back" +"bind a +left" +"bind d +right"')
Do note that these changes may persist between vizdoom launchers. E.g. if you unbind keys, you have to rebind them again to use them later.

Hi @Miffyli
Thanks for your quick reply.

I have tried to add that line to spectator.py https://github.com/mwydmuch/ViZDoom/blob/a3367d9dd59b47493a14606e19752e9ade639ba0/examples/python/spectator.py instead of line 36 and it didn't work.

Any suggestions on how I can debug it ? I am using latest vizdoom with anaconda3

Hmm with that setup it works for me (Windows 10, Python 3.5, VizDoom 1.1.0). I don't think change in version should have an effect here as this is zdoom level stuff.

Here are the lines 33-44 I used just in case. Other than that I do not know what to say to debug this :(

# Enables freelook in engine
game.add_game_args('+"bind w +forward" +"bind s +back" +"bind a +left" +"bind d +right"')

game.set_screen_resolution(ScreenResolution.RES_640X480)

# Enables spectator mode, so you can play. Sounds strange but it is the agent who is supposed to watch not you.
game.set_window_visible(True)
game.set_mode(Mode.SPECTATOR)

game.init()

Hello @emansim,
when you launch an instance of vizdoom, it will create _vizdoom.ini in your working directory (if it doesn't exist yet). This file contains all the additional engine settings, including key bindings, you can edit it freely.

You can save it in some better location and load using this function:

I modified _vizdoom.ini and it worked for me ! Thanks.
