You create a layer with your map editor (I use tiled), you use a set of W&B tiles for the collision mask and you set your layer invisible. It appears this way in the tmx : <layer name="collisions" visible="0" width="180" height="120"> <data encoding="base64" compression="zlib"> ... </data> </layer> Of course, you have to code your own routine to check collision. Personnally, I used numpy.arrays of boolean for representing each "collision_tile". I wrote a function collision(collision_layer, collision_tiles, x, y) to check if the bit at position (x, y) on the layer is masked or not, then I test only the pixels on the edge of the object I want to test. It was fast enough on my first attempt, but my second being more ambitious, I'll use numpy abilities to work on entire array. -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
