Thanks for playing! Wait 1 second after pressing e because the duration of the open and close animation is 3 seconds total and it takes 1 second for the animation to start playing the keyframes. The slow pacing is intentional if you find it annoying haha.
set a cooldown on the animation trigger, its pretty simple if you use unity
heres a description
1) Add an Animation Event to your last key frame.
See https://docs.unity3d.com/Manual/animeditor-AnimationEvents.html
2) In Update you can continuously check if the animation has completed.
See AnimatorStateInfo
3) Start a coroutine that yields and waits for the animation to complete.
4) Use StateMachineBehaviour
hope this helps, unless im stupid and ur not using unity, if not lemme know and ill figure out how to fix it lol
