to implement keysupport is easy as well, just few lines of code.
@Ruleofzu are you sure about the price? you ever tryed to make it? and the demo is just an example , its not only the code, most ppl just wanted to know HOW they make it, so iam going to give the Code and explain what i did and why , it isnt somethink like "Pay me and get the zip and make what ever you like"
@a_bertrand
ok i will implement more layers, A* Algorithm , key functions, collision check , i hope after it you will agree with the price, just give me few days
