Thanks a lot Joshtek :) sadly i have not enough motivation and time for coding better SFX and resolving some strange collisions.
It's just about the hitbox when i choose their position in the level :
There no big bug in the collisions but it's because the collision system i code is so accurate that when i don't carry a Platform Slope hit box at the good position the character stop because there is a little pixel that blocking him on the slope. If i take more time to change the position of some platform's hitbox theses collisions problem can be solves.
My slope collision system i code is based on a fastLoop named "Slope" and this system can start only if there is 1 small pixel of slope when the character walk on the slope he approching. If the slope have a too higher position : The slope colliision loop detect litterally a wall even if it's just a simple slope and so the character is blocking.
When the collision of the slope is good :
_______________
|\ | character |
|_ \_|_______________|
When the collision of the slope is not good and the character doesn't detect a slope behavior with the slope fast loop.
|\ _______________
|_ \ | character |
|_______________|
Thanks for commenting aboutthe drawing and graphic of the game : i take a lot of time on it for this gamejam and don't take enough time on coding.
