When it comes to write down a program to follow, i'm not very good!!! (And that's funny because i'm a developer, write programs it's supposed to be my job!!! XD) But you provided me a general program, so thank you, i'll use that as a reference!!!
I haven't really considered that before, but i think that modesing it's better than sprites in my case because i'm already confident with them, and if i have to do sprites i'll have to learn hot to do it and, of course, i have to draw it, which a'm no good at all!! But maybe code-wise it's much simple to implement, so i'll give it a quick think!!
Thank you for the support and especially for the chart!!!
