Hi,
I recently downloaded and installed Dark GDK and wanted to make a simple pong game, but I get some errors, which I can't fix.
I looked several times through the code but to me it looks just fine.
Here are the files (they're also attached)
ball.cpp
#include "DarkGDK.h"
#include "paddle.h"
#include "ball.h"
Ball::Ball( int px, int py, int pradius, int pdirX, int pdirY )
{
x = px;
y = py;
radius = pradius;
dirX = pdirX;
dirY = pdirY;
return;
}
int Ball::GetX() const
{
return x;
}
int Ball::GetY() const
{
return y;
}
int Ball::GetRadius() const
{
return radius;
}
void Ball::Update( const Paddle& ppaddleLeft, const Paddle& ppaddleRight )
{
// move ball
x += 1*dirX;
y += 1*dirY;
//check on collision with the bounds
if( y - radius <= 0 )
dirY *= -1;
if( y + radius >= 600 )
dirY *= -1;
//if( x - radius < 0 )
//if( x + radius > 800 )
// check on collision with the paddles
if( y - radius > ppaddleLeft.GetY() - ppaddleLeft.GetL()/2 && y + radius < ppaddleLeft.GetY() + ppaddleLeft.GetL()/2 )
{
if( x - radius <= ppaddleLeft.GetX() + ppaddleLeft.GetW()/2 && x - radius > ppaddleLeft.GetX() - ppaddleLeft.GetW()/2 )
dirX *= -1;
}
if( y - radius > ppaddleRight.GetY() - ppaddleRight.GetL()/2 && y + radius < ppaddleRight.GetY() + ppaddleRight.GetL()/2 )
{
if( x + radius > ppaddleRight.GetX() - ppaddleRight.GetW()/2 && x + radius < ppaddleRight.GetX() + ppaddleRight.GetW()/2 )
dirX *= -1;
}
return;
}

dbCircle( x, y, radius );
return;

I hope someone can help, because I'm really dispair of these eror messages.
Thank you in advance and sorry for the not very descriptive thread title.
