setPosition to negative value
« on: March 19, 2013, 02:54:47 pm »
I have a circleshape and I set it's position like this
curView.setTextureRect(IntRect(cursorX - cursorV, cursorY - cursorV, cursorV*2, cursorV*2));
cursorV is the the radius of curView

But if cursorX - cursorV or cursorY - cursorV results in negative then the circle dosen't display at all. (so I had to limit the result to zero)
How do I go around that?

And what did you expect to see, when using an area which is outside the source texture?

(forgot to mention) This is how I set the position of the circle.
curView.setPosition(cursorX-cursorV, cursorY-cursorV);

So, if I make my texture curcorV larger to the top and left and add +curcorV to all my texture related calculations, but keep the above writen position setting will it then display the circle correctly?

Just tested that. And apperently position can't be negative either.

So how do you do that?

How do you do what? Please explain what you're trying to do, it's not clear at all.
