Explosive Damage and Force with Obstructions | Unity Tutorial
Explosions are a powerful and fun effect to add into your game. In this tutorial we'll add point-and-click explosions to both apply damage, and knock back Rigidbodies in a scene. We'll also implement relatively simple method o determining if a wall is in the way of the explosion. If there is some obstruction, then we'll say the explosion won't affect the object on the other side.
Using a Rigidbody allows us to capitalize on Unity's physics engine to apply knock back force based on the explosion position and explosive force. We'll play with some different explosive force values to see the difference between values like 1,000 and 5,000 on some Rigidbody barrels.
I'll show how you can calculate the damage value with a linear falloff from the explosion point. You can follow the same math and apply a custom AnimationCurve if you would like to apply a more complex damage falloff curve.
