Unity 3d collectible coins physically apply force to the player - Stack Overflow

I created a dynamic coin. This coin moves like a normal object, hits the ground and is affected by gravity. When I collect this coin with my player object, I can destroy it, but just before it is destroyed, if the coin has a speed, a force affects the player. (Like getting a punch from where the coin came from). I can't make the coin isTrigger because it needs to interact normally with other objects. I can't make the player kinematic because it needs to interact normally with other objects. When I do "Physics.IgnoreCollision(playerCollider, coinCollider);", I can't collect the coins. OnCollisionEnter doesn't work because I don't want a collision and the coin to physically apply force to the player. OnTriggerEnter doesn't work either because isTrigger is closed. Please, how can I solve it?

I would simply add a child to the player on a different layer - let's call it COINCOLLECTOR with a simple Trigger collider (sphere for instance). Probably doesn't have to be a mesh collider and you can save some performance that way.

Then configure the layers so that only the player child trigger interacts with coins, not the player itself.

This way

• COINS just keep interacting with basically all you already had
• PLAYER also keeps interacting with the rest of the world
• PLAYER does NOT collide with COINS so there will be no physics impact caused by the coins
• but COINCOLLECTOR can collect the COINS using a trigger
