I’m working on a simple breakout game and I’ve problem with
ball:addEventListener( “collision”, removeBricks )
, it works fine until the ball hits two bricks at same time, than the up/down direction (vy) switch twice, making the ball continue moving up or down.
How can do one by one addEventListener collision and disable multiple collides at once?
function removeBricks(event)
if event.other.isBrick == 1 then
vy = vy * (-1)
…
end
end
You can simply try another if check to work around that problem.
[LUA]
function removeBricks(event)
local other = event.other
if other.isBrick == 1 then
if vy < 0 and other.y < self.y then
vy = vy * (-1)
elseif vy > 0 and other.y > self.y then
vy = vy * (-1)
end
other:removeSelf() – or wathever you want to do with the block
end
end
