Flip Sprite

Tstar_one

Hello Guys i need help

I want to flip an Sprite . if i do this with setSccaleX(-1) and setScaleY(-1) the Sprite is left from where the object shoud be
so what i have to do ? i use Texture with Region for the Anmimation

I think setting anchor point to 0.5, 0.5 should solve that problem, have you tried?

hm yeah works but i need the AnchorPoint at 0 , 0 for Collision an other Functions :S is there any thing i can do ?

hmm, what exactly your collision function does? Can't it use Sprite:getBounds() for collision determination?

Standard Code from the Forum

function sprite:collision(sprite2)

--Input (sprite2): another sprite to check for collision detection
--Return: return true if the rectangles overlap otherwise return false

-- self bottom < other sprite top
if self:getY() + self:getHeight() < sprite2:getY() then
return false
end
-- self top > other sprite bottom
if self:getY() > sprite2:getY() + sprite2:getHeight() then
return false
end
-- self left > other sprite right
if self:getX() > sprite2:getX() + sprite2:getWidth() then
return false
end
-- self right < other sprite left
if self:getX() + self:getWidth() < sprite2:getX() then
return false
end

return true
end


how can i include code here ? : )

you most probably can replace it with this:

function Sprite:collidesWith(sprite2) local x,y,w,h = self:getBounds(stage) local x2,y2,w2,h2 = sprite2:getBounds(stage)   return not ((y+h < y2) or (y > y2+h2) or (x > x2+w2) or (x+w < x2)) end

Fantastic thank you very much again
