Detecting Collisions (OnCollisionEnter) - Unity Official Tutorials

Detecting a collision in Unity requires one of the two colliding objects to contain a script with an OnCollisionEnter function in. The basic syntax takes a single argument of type Collision. >From this you can query the collision to find out information about the object that has been collided with. In this example our samoflange ball is bouncing around with a bouncy physic material and hitting power cubes. The script attached to the ball looks like this. Currently we have nothing inside the func

tion. We can make use of the collision argument to check for when it has hit a power cube. We simply use an IF statement and check 'col', our variable, for the data it contains. One example of which is the game object that it's collided with and as a result, the name. We would say if(col.gameobject.name) is equal to the hierarchical name of the power cube which is 'prop_powercube' and now this IF statement will only activate when our ball collides with our power cube. If it does collide, we'll m

ake use of the Destroy command. You can check what types of data you can retrieve from the collision by typing the name of the variable and then typing a dot (period) in the script editor. You'll then see a list of the various different data you can retrieve from the collision. Also remember to check the script reference page linked below on the collision class to see other data that you can retrieve. For now we'll simply destroy the game object. And when we save our script you'll see that whene

ver a collision occurs our ball destroys a power cube. Subtitles by the Amara.org community
