For what you need an example? I don’t have a jumpscare example unfortunately.
ok you mean like a picture pops up with a loud noise and sound effect?
Yes, I would start with that. You can improve it when you are done.
bu I dont have a 2d image of the 3d model monster what do I do?
You can search for a look-alike image. You can also create one yourself, for example start with a screenshot of your 3D model.
ok I got my image now how do I make it appear when the monster attacks in the enemy ai script ya made
I have already shared the code. Replace your current window.location.reload(); with it.
ok thanks
I want it to trigger the jumpscare, wait one second, then stop or refresh the window
I use 5 seconds in my code example above.
ok uh do I make this a seperate script or do I put it in enemt ai?
As far I have seen you use this somewhere in your enemy AI script.
would the image be a sprite or a 2d screen?
It would be a child entity of your 2D screen with an image element component.
ok
it does not work 
it is supposed to enable the name of the 2d image
else if (this.enemyState === 'Attack') {
this.enemyDestination.copy(new pc.Vec3(this.enemyTarget.getPosition().x, this.entity.getPosition().y, this.enemyTarget.getPosition().z));
this.entity.lookAt(new pc.Vec3(this.enemyDestination.x, this.entity.getPosition().y, this.enemyDestination.z));
this.jumpScareEntity.enabled = true;
this.Jumpy.enabled = true;
}
If something doesn’t not work, you have to figure out why it doesn’t work.
is there a different window code
I want the window to just stop, not refresh
What do you mean with ‘just stop’? If you mean leave the jumpscare image on the screen, then remove window.location.reload();.
What about teleporting the player back to the original spot?
