There are four passes, on each pass only effective items for that pass are drawn. So the first pass of sprites only renders regular sprites, and the second pass only renders priority ones. The same...

Unfortunately yes, I can only give support for Tilengine itself, not for other bindings. But I can take a look, maybe I can see something suspicious

Hi! You can do this as long as you first call: Code: -- TLN_DisableLayer(myLayer) -- If not, you'll be deleting a resource that is attached to an active layer, that will cause a segfault on...
