You have an animation "bend".
You have the controls for the platform behavior set on 'custom '
Assuming you press arrow up to jump.
In base you want to delay the jump. And we gonna use the animation "bend" to accomplish this.
So.
On key (up arrow) pressed
____ set the animation to "bend"
On finished (animation "bend")
____ Simulate control (jump)
Be aware that you have to cage the other animations.
So where ever you start the another animation .... add the condition 'Is playing ("bend") <---- inverted.
