SpriteBatch does not support removing individual sprites. One can do a pseudo removal (instead of clearing and re-adding everything) by:

 +
<source lang = 'lua'>
 +
SpriteBatch:set(id, 0, 0, 0, 0, 0)
 +
</source>

This makes all the sprite's vertices equal (because the x and y scales are 0), which prevents OpenGL from processing the sprite when drawing the SpriteBatch.

Available since LÖVE 0.8.0

Arguments

number id
The identifier 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).

Notes

SpriteBatch does 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 OpenGL from processing the sprite when drawing the SpriteBatch.
