Gamemaker Day 68

Today I learned what collision masks does, what i did : I find out that the player animation would stick into a wall sometimes, so I did a little changes in the player object. on the player object , i set the mask option to the sprite wall. this will make sure that the player pixel won't touch the wall pixel. so that whenever the player colliding with the wall, it won't stick into a wall for sure.

the next day I'm going to watch the tutorial "variable jump" , to make the jump of the player feel more real.
