hi... which method can I use to update the screen and clear the scene durin=
g
an animation? SDLSurface.blit() and SDLSurface.updateRect() don=B4t do that=
.
The result is a track of my main surface when I move it by keyboard event.
hi... which method can I use to update the screen and clear the scene durin=
g
an animation? SDLSurface.blit() and SDLSurface.updateRect() don=B4t do that=
.
The result is a track of my main surface when I move it by keyboard event.
my main loop code :
private void mainLoop() {
while(true){
try {
mainsurface.checkEvent(SDLEvent.pollEvent());
mainsurface.blitSurface(screen);
screen.flip();
}
catch (SDLException e) {
e.printStackTrace();
}
}
}
