Tile sizes & view limit

by John Coyne · in Torque Game Builder · 01/22/2006 (5:11 am) · 5 replies

Hi
I'm making an 8 way scrolling map for my game, on a map thats 2 screens tall and wide. Trouble is setting the view limit and the tile size, i'm not sure what the recommended tile size is, i'm using 10 just now. How do i figure out the tile size and number of tiles to get the correctly sized map, and how should i set the view limit. Just now it seems a lot of trial and error. Also, will there be problems later when someone using a different screen resolution runs the game?

It's all up to you. T2D's coordinate system is not dependend on screen resolution or anything.

You can set the area the camera view with t2dSceneWindow::setCurrentCameraPosition(%pos, %size).
E. g. you do SceneWindow2D.setCurrentCameraPosition("0 0", "100 75") and have a tile-size of 10x10 then there would 10x7,5 tiles be shown per screen. If you're tilemap was 20x14 tiles, that would be what you wanted.
You can then set the view-limit to the size of your map:
SceneWindow2D.setViewLimitOn( $yourTilemap.getTileLayer(0).getArea() );

It is always recommended that the width and height ratio of your camera is the same as the one of the t2dSceneWindow. Otherwise things will get stretched or squashed.

For some reason getArea isnt working for me?
Is this a newer function?

I think, it is available since t2d 1.1 alpha1.
