The "Apply Radial Damage" node is used to cause damage to multiple objects within a specific area of effect. It simulates an explosion or impact that affects nearby objects. Example: Let's say you have a game where the player controls a spaceship equipped with missiles. When the player fires a missile at a group of enemy spaceships, you can use the "Apply Radial Damage" node to create an explosion. The explosion damages all enemy spaceships within its radius, potentially destroying multiple enemies with a single missile.
