Hi I have a problem with this function I can't wrap my head around it I don't seem to understand how to use it  can somebody please help me understand this function? Here is a simple script for walking
if(key_w == ON || key_d == ON || key_s == ON || key_a == ON){
if(key_w == ON && key_s == ON || key_a == ON && key_d == ON){
ent_animate(me,"stand",my.skill1,ANM_CYCLE);
my.skill1+=5*time_step;
my.skill1 %= 100;
my.skill2 = 0;
}else{
ent_animate(me,"walk",my.skill2,ANM_CYCLE);
if(my.skill2 <= 100){
ent_blendframe(me,NULL,"walk",6,my.skill2);
}
my.skill2+=1*time_step;
}
} else{
ent_animate(me,"stand",my.skill1,ANM_CYCLE);
my.skill1+=5*time_step;
my.skill1 %= 100; my.skill2 = 0;
}
it runs within a while loop but I can't get ent_blendframe to work properly. any suggestion? thanks a lot for reading.

I've been experimenting with it trying to blend one animation to the next one but I get this kind of snapping, as if it's skipping animation frames. as my exmaple above I have ent_blendframe(me,NULL,"walk",6,my.skill2); so help me understand what should go in the fourth parameter? I tried 0 and even the my.skill1 and 2 with no smooth blending results. according to the documentation the fourth parameter is: anim_percent Percentage within the target scene, 0..100 but what does this exactly means? thanks for answering superku

Blending doesn't work too well with vertex animations, you can only blend between two full (integer) frames.
Imagine the following scenario:
"walk" consists of 10 frames, my.skill2 is 37. After the instruction
ent_animate(me,"walk",my.skill2,0);
your model's mesh will be blended by 70% from walk frame 3 to frame 4.
When you now call
ent_blendframe(me,NULL,"stand",6,75);
you try to blend the walk frame 3.7 and the stand frame 0.6 but as you can only blend between integers resp. the "entity.frame" and "entity.next_frame" parameters, the result will be a blend of walk frame 4 (or 3, I don't know if the function searches the closest or the next-lower integer) and stand frame 1 (or 0). Thus there will be some kind of snapping.
It's very hard to explain, especially in English, just keep in mind that ent_animate and ent_blendframe (probably) only set the frame and next_frame parameters, the resulting mesh is calculated afterwards before rendering.
EDIT: What you can try is to let an animation reach a full integer frame and then blend to another integer frame of the stand cycle.
