The above are batched together into a single draw call when called without other drawing calls in between, as long as the following criteria are met: - The texture is the same. - The primitive type is the same (points cannot be batched with non-points). - The love.graphics state is the same (aside from the current color - i.e. setColor - and the transform state). - The active shader’s uniform values are the same. You can examine the ‘drawcalls’ field of love.graphics.getStats() to help determine if your code is allowing for optimum batching. --HG-- branch : minor
