You're going to have to analyze your sprite for opacity, like DMGreg mentioned. Check each pixel, if it has alpha of less than 255, create a 1-pixel large collider. This will have performance issues with high-res maps. We'd probably need more context on why you need this method to suggest other avenues of action. | |
