i have an issue where the particle system on the ballista doensnt collide with the game object, and it just goes through it. I have the box collider on the game object but for some reason they dont collide.
Welcome to the community. Check to see if you set the collider to “Is Trigger”. Triggers to not stop objects, they ignore physics and just register that a collider entered another one.
i just checked, and “is Trigger” is not set on.
Hi MJ28,
Welcome to our community! 
Could you please share screenshots of what you did and see in your game in Unity? At the moment, we do not know anything about your game, so it is difficult to help.
