MeshInstances

Holds the per instance data for Renderer:drawImageMeshInstanced. Unlike the mesh buffers it is meant to be rewritten every frame.

​

Methods

​

resize

resize(count: number) -> ()

Sets the number of instances.

local mi = MeshInstances()
mi:resize(3)

​

set

set(index: number, transform: Mat2D, opacity: number?, additiveness: number?, uvTranslate: Vector?, uvScale: Vector?) -> ()

Writes the instance at index, which is zero based. Everything past transform is optional.

local mi = MeshInstances(2)
mi:set(0, Mat2D.withTranslation(Vector.xy(10, 20)))
mi:set(1, Mat2D.identity(), 0.5, 0, Vector.xy(0, 0), Vector.xy(0.5, 0.5))
