Collider_Check()

bool Collider_Check	(	Collider *	collider,
		ColliderCheckResult *	checkResult
	)

[PostUpdate] Checks if a collider is intersecting with any of its collider layers.

Check for collisions with a collider.

This function checks for collision between a collider and everything else in the ColliderList array. Any colliders whose layer is not in the input collider's collidesWith section will be ignored.

Parameters

collider	The input collider
checkResult	The checkResult of the collider, which includes 2 members: checkResult.objects: an array of detected colliders checkResult.count: number of collisions detected

Returns

true if collision detected, false otherwise

Collider_Register()

void Collider_Register	(	Collider *	collider,
		void *	owner
	)

[Start] Registers a collider to the Colliders array.

Register a collider with the collision manager.

This is so that every colliders can be checked by each other.

Parameters

collider	A pointer to the collider struct. For example: &player.state.collider
owner	A pointer to the owner of the collider. For example: &player

Collider_Reset()

void Collider_Reset

(

Collider *

collider

)

Deactivates a collider and resets its properties.

Deactivates a collider.

Parameters

collider

The collider to reset

Collider_Start()

void Collider_Start

(

)

[Start] Initializes the Colliders array.

Initialize the collision manager.
