General / Clamp to Screen

« on: April 27, 2011, 05:49:15 am »

Thanks for the reply! And thanks for pointing out my mistakes >.<

But I'm still not able to get it working correctly. I did change the function and the playerBoundingBoxY is supposed to be playerPositionY, thought code::blocks auto-entered the correct one while typing. my bad.


even after those corrections i'm still able to travel outside the window. I'll keep at it and try it in a new project because my code is a mess of different tutorials right now.

General / Clamp to Screen

« on: April 27, 2011, 04:04:36 am »

Hello!

This is my first time posting and I'm in a bit of a pickle. I started to use SFML for a game and I'm working on the basics of the library. Now, I'm probably totally missing something here but is their a way to bind a character to the screen? As in not allow them to go off screen?

In XNA their is a function called Clamp that is used to do this and I tried to recreate it here but it doesn't work.

Code: [Select]


float Clamp(float value, float min, float max)
{
    if(value < min)
    {
        return min;
    }
    if(value > max)
    {
        return max;
    }
    if(min <= value || value >= max)
    {
        return value;
    }
}

//in game loop
    playerPositionX = Clamp(playerPositionX, 0, windowWidth);
    playerBoundingBoxY = Clamp(playerPositionY, 0, windowHeight);



Any help would be much appreciated. As I said, I'm probably just not seeing the obvious answer.[/code]
