You need to give every animation scene of your Model a Name.
Example:
stay-1 to stay-10
walk 1 to walk 20
jump 1 to jump 5
...etc...
In the ent_animate, you just Write the scene Name into the stringpart, to Show the scene.
Example:
ent_animate(my, "stay", my.skill99, ANIM_CYCLE);
my.skill99 += ...etc...
If your Model is finished with all animations.. And you gave them all the Same Name.. You got à Problem.
