Hi.

I'm creating and multi-player tanks game using one keyboard (so player one gets the up, down, left and right key, and player two gets the w, a, s and d keys), and I wanted to split the screen so that player one sees one view and player two sees another.

How would I do this?

You could have 2 additional cameras, and have each one render to an image (set camera to image). These 2 images would be what the useers see (as sprites or pasted images)

or simply use the Set Camera View Command to specify the area on screen the camera-images will be rendered to...

In a game I am working on I used the following function to set up separate 'windows' for each of the two players:


This function is called once before your main loop.

During the main loop, I do something like this for each of the players:

The floating variables, dist# and high#, are made as globals and are set earlier in the code to: dist# = 6.0 : high# = 3.5. This works with what I am working on, but you will likely need to adjust it for your game.

You wouldn't normally need the extra object in there like I have done, but this code is using Dark Physics, and is necessary. You should get the idea.

Don't forget to use the Set Camera Aspect command if you don't want to have everything stretched. The aspect ration should always be renderSizeX/renderSizeY (don't forget to use floats values).
