  • In game development, a collider determines how objects interact when they come into contact.

Examples

  • I got everything working perfectly physics-wise with five box colliders attached to each object.

  • The same is true for adding or removing a collider.

  • Even changing the size of a collider can have a significant effect.

  • Why does changing a collider affect rigid body physics?

  • Why does changing a collider, say from a box to a capsule, change the way the object is affected by a force?

  • But on occasion, even though the colliders are very thin, an object would land on its edge.

  • I thought the rigid body determined how a body reacts to applied forces, while the collider only affects the object's interaction with other objects.

  • I thought switching to capsule colliders with round edges would solve this problem.

  • The problem I'm trying to solve involves changing from box to capsule colliders.

  • I've been disappointed with the standard CharacterController offered as the default capsule collider; it just isn't well suited for a 2D platformer game.

Surface Forms

collider singular
colliders plural

Morphology

collider = collide (transparent) = collide + er

The software term names the component related to collisions and is transparently built as 'collide' + '-er' (agent/instrument).

Etymology

Collider comes from Latin parts com- 'together' and laedere 'to strike'. That same idea of things 'striking together' explains the game meaning: a game collider is the shape on an object that tells the game when objects hit or bump into each other.
