Hi, I'm sorry if this is the wrong place to post this, but this was the only place I could find to discuss pyglet programming. I'm currently trying to move a 2d game system over to pyglet from pygame. In the pygame code, collision is checked for using a bitmap, allowing the level to contain arbitrary curves and still react correctly. I am trying to replicate this behavior.
The way I am currently doing it is as follows: I read an image in from file. I convert that image to its data. I take a region of the data which is one pixel known to be fully transparent. I change the format for that region to 'A' (Alpha). Then, whenever I'm checking for collision, I take a one pixel region at the x and y coordinates, convert the format of that to 'A', and compare the value of its data to the value of the sample pixel's data. If they aren't equal, a collision has occurred. Converting the format of an ImageData or ImageDataRegion is very expensive, though, and slows my program down to a crawl. Is there any way to get the Alpha without performing this operation, or is there a better way to do this?
