Imagine an isometric actor. (Such as a spike)
Look at the attached image. Actors will be spawn in that order forever.
(For example; The spike will be spawned at a certain coordinate such as 326,140. Its x-speed is -8, y-speed is 4. So they will move to SW. If x of last created actor is 320 a new spike will be spawned and will be sent back of a layer. Actually, i did this thing but the order of spikes are not regular. I can also send my sample to you. )
You can send private message to me.
NOTE: Please don't send a message if you don't have enough Stencyl expertise. I have some experience about paid works. It looks easy but it is not. Layer ordering needs a complex behavior. I also tried the behaviors on StencylForge but they are not work with these kind of layering.
