| This method is not supported in earlier versions. |
Changes a sprite in the batch. This requires the sprite index returned by SpriteBatch:add or SpriteBatch:addLayer.
Contents
Function
Synopsis
SpriteBatch:set( spriteindex, x, y, r, sx, sy, ox, oy, kx, ky )
Arguments
number spriteindex- The index of the sprite that will be changed.
number x- The position to draw the object (x-axis).
number y- The position to draw the object (y-axis).
number r (0)- Orientation (radians).
number sx (1)- Scale factor (x-axis).
number sy (sx)- Scale factor (y-axis).
number ox (0)- Origin offset (x-axis).
number oy (0)- Origin offset (y-axis).
number kx (0)- Shear factor (x-axis).
number ky (0)- Shear factor (y-axis).
Returns
Nothing.
Function
| Available since LÖVE 0.9.0 |
| This variant has replaced SpriteBatch:setq. |
Changes a sprite with a Quad in the batch. This requires the index returned by SpriteBatch:add or SpriteBatch:addLayer.
Synopsis
SpriteBatch:set( spriteindex, quad, x, y, r, sx, sy, ox, oy, kx, ky )
Arguments
number spriteindex- The index of the sprite that will be changed.
Quad quad- The Quad used on the image of the batch.
number x- The position to draw the object (x-axis).
number y- The position to draw the object (y-axis).
number r (0)- Orientation (radians).
number sx (1)- Scale factor (x-axis).
number sy (sx)- Scale factor (y-axis).
number ox (0)- Origin offset (x-axis).
number oy (0)- Origin offset (y-axis).
number kx (0)- Shear factor (x-axis).
number ky (0)- Shear factor (y-axis).
Returns
Nothing.
Notes
SpriteBatches do not support removing individual sprites. One can do a pseudo removal (instead of clearing and re-adding everything) by:
SpriteBatch:set(id, 0, 0, 0, 0, 0)
This makes all the sprite's vertices equal (because the x and y scales are 0), which prevents the GPU from fully processing the sprite when drawing the SpriteBatch.
