Draw a sprite by replacing the existing content completely.

Parameters

  • x,y The coordinates of the top left pixel location.
  • bitmap A pointer to the array containing the image frames.
  • frame The frame number of the image to draw.

A sprite is drawn by overwriting the pixels in the buffer with the data from the specified frame in the array. No masking is done. A bit set to 1 in the frame will set the pixel to 1 in the buffer, and a 0 in the array will set a 0 in the buffer.
