Command Index · Blitz3D · Physics

PhysicsOverlapSphere:Int32 x:Float32, y:Float32, z:Float32, radius:Float32, mask_low:Int32=-1, mask_high:Int32=-1, sensors:Int32=0, world:Int32=0

Parameter	Mode	Type	Default	Description
x	In	Float32	required	The middle of the sphere, x.
y	In	Float32	required	The middle of the sphere, y.
z	In	Float32	required	The middle of the sphere, z.
radius	In	Float32	required	The radius, more than 0.
mask_low	In	Int32	-1	The layers to look at, as bits 0 to 31 of a mask (bit n is layer n). -1 (default) looks at all layers.
mask_high	In	Int32	-1	The layers 32 to 63, as bits 0 to 31 of a mask. -1 (default) looks at all layers.
sensors	In	Int32	0	1 also finds sensors (see PhysicsSensor); 0 (default) leaves them out.
world	In	Int32	0	The physics world, 0 (default) for the default world.

Returns: How many bodies touch the sphere.

Description

〔BlitzLLVM〕 This command does not exist in the original Blitz products. BlitzLLVM adds it.

Finds the bodies of a physics world that touch a sphere. The bodies are kept in the order they were made; read them with GetPhysicsOverlap until the next overlap query.

Differences

• The original has no such command. This is an extension; programs that use it do not compile with the original Blitz3D.
