I want to mirror an image...
I know Scale -1.... but I',m rotating it arround different center, so i need to set the new rotation center for the mirrored image and the rotation point... but it's very hard to do since the negative scaling doesn't seem to work as i expected...

It doesn't work as expected, or that's what I expect (:P). Anyway, rude knows the problem, so let's wait for 0.6.0.

When is 0.6.0 released? I mean if that's in several month that would be waiting month before I can go on in gfx design....

Months. Many many months.

There's of course always the simple solution of making flipped graphics in the actual image files.
Not a good solution, but it gets the job done.

I found an algorithm mirroring images with different center. Very strange functions i needed.. adjusted it by foot. I have a 1px error and it works with all 3 images I am using....
If this is the code of displaying the image "normall"
Code: Select all
MYIMAGE:setCenter(MYIMAGEROTATIONCENTERX,MYIMAGEROTATIONCENTERY)
love.graphics.draw(MYIMAGE, xpos-MYIMAGEToOverallCenterX, ypos-MYIMAGEToOverallCenterY, ANGLE, 1, 1)
Here the corresponding code for the mirrorred image
Code: Select all
MYIMAGE:setCenter(MYIMAGEROTATIONCENTERX+3*MYIMAGEToOverallCenterX+MYIMAGE:getWidth()-5,MYIMAGEROTATIONCENTERY)
love.graphics.draw(MYIMAGE, xpos+MYIMAGEToOverallCenterX-1, ypos-MYIMAGEToOverallCenterY, ANGLE, -1, 1)
MYIMAGEToOverallCenter is the relative position to the players center. This makes absolutely no sense to me to integrate this in the set center function but NOTE: this is working for my Charakter in the game with all images i tested with +-1p... so close enough to use it...
If someone finds out the exact sollution PLEASE tell me!!!
