Feature requests / Some ideas

« on: May 13, 2008, 01:38:04 pm »

It would be nice if Sprites had separate centers for scale, rotation, and position.
I also don't like it that when you scale a sprite, the rotation center doesn't stay in the  center of the sprite.

A function for checking overlaping of sprites would be nice. It should also consider scale and rotation of the sprites.

bool sf::Sprite::Collides(const fs::Sprite &s1, const fs::Sprite &s2);

So if two non-trasparent pixels of the sprites would overlap, the function would return true.

Btw why have Sprites a method called Scale() and another called SetScale()? Do they differ in any way?

Window / Bug in event TextEntered?

Hello

I wrote a program that displays text the user enters, but when one presses backspace it won't react to any subsquent input. Is this a bug?

General discussions / PostFX - random numbers?

« on: May 11, 2008, 01:54:40 pm »

Hello

Anybody knows how to generate random numbers in glsl? I'm trying to write a blur effect with jitter. I know there are functions like noise1, noise2 etc. but somehow they seem not to do anything but return zero. Maybe I'm doing something wrong?

best regards
