TAgkPhysics.RayCastCategory Method (Cardinal, TAgkPoint, TAgkPoint)
|
AGK for Pascal
|
|
|
Casts a ray through all physics objects including sprites that have physics turned on and stores the closest item hit.
|
Parameters |
Description |
|
const Categories: Cardinal |
The categories to check for intersection with the ray, bitwise field using the lower most 16 bits. |
|
const P1: TAgkPoint |
The start point in world coordinates. |
|
const P2: TAgkPoint |
The end point in world coordinates. |
True if there was a collision, False if not.
Results of a ray cast can be retrieved using the other ray cast functions and properties such as RayCastNormal.
If the ray starts inside a shape that shape will not be counted in the results.
This function filters the sprites that are checked so only sprites of certain categories are checked. The category parameter is a bitwise field that uses the lower 16 bits to represent each of the possible 16 categories used when setting up a sprite. The default value of all 1s means all categories will be included, whereas a value of all 0s means no categories will be included. You can set individual bits to set which ones should be checked.
