Could just use a simple script like this..
PHP Code:
//#CLIENTSIDE
function onCreated() {
setTimer(0.05);
}
function onTimeout() {
with (findimg(200)) {
x += 4;
if (x > screenwidth) x = -32;
y = screenwidth / 2;
layer = 4;
image = "block.png";
}
setTimer(0.05);
}
The block's movement will become noticeably jerky when the timeout glitch starts happening.
