This function is not supported in earlier versions.

Draws many instances of a Mesh with a single draw call, using hardware geometry instancing.

Each instance can have unique properties (positions, colors, etc.) but will not by default unless a custom Shader along with either per-instance vertex attributes or the love_InstanceID GLSL 3 vertex shader variable is used, otherwise they will all render at the same position on top of each other.

Instancing is not supported by some older GPUs that are only capable of using OpenGL ES 2 or OpenGL 2. Use love.graphics.getSupported to check.

Function

Synopsis

love.graphics.drawInstanced( mesh, instancecount, x, y, r, sx, sy, ox, oy, kx, ky )

Arguments

Mesh mesh
The mesh to render.
