High there, I am using something similar to the SDK so I think I am in the right place, basically I've got a wrapped c++ version of Blitzmax and I'm having problems with basic collisions within a class, i.e. comparing itself with other objects created by using an iterator to scroll through a list, I've converted the rectsOverLap function. In Bmax the way you stop an object from comparing itself with itself is:
If obj:TObject <> Self Then
Do collision
Here is my code at the moment which simply draws a rectangle for every player created and in the update() it's looking through the list do a rects overlap, but it's not working, I think it's the if(*iter ? ! this : false), but I'm not sure what to do?
using namespace std;
class CPlayer
{
public:
CPlayer(double x, double y)
{
this->m_x = x;
this->m_y = y;
this->m_list.push_back(this);
}
virtual ~CPlayer(){}
void draw()
{
ezSetColor(150, 150, 150);
ezDrawRect(this->m_x, this->m_y, 32, 32);
update();
}
double getX()
{
return this->m_x;
}
double getY()
{
return this->m_y;
}
void update()
{
list<CPlayer*>::iterator iter;
for(iter = this->m_list.begin(); iter != this->m_list.end(); iter++)
{
double pos_x = (*iter)->getX();
double pos_y = (*iter)->getY();
if(*iter ? !this : false){
if(this->rectsOverlap(this->m_x, this->m_y, 32, 32, pos_x, pos_y, 32, 32)){
ezSetColor(255, 255, 255);
ezDrawText("C", this->m_x+5, this->m_y+5);
}
}
}
}
bool rectsOverlap(double x0, double y0, double w0, double h0, double x2, double y2, double w2, double h2)
{
if(x0 > (x2 + w2) || (x0 + w0) < x2) {return false;}
if(y0 > (y2 + h2) || (y0 + h0) < y2) {return false;}
return true;
}
private:
double m_x, m_y;
list<CPlayer*> m_list;
};
//Write your game/application here
void ezRunApp()
{
ezGraphics(800,600,false);
CPlayer player1(40, 40);
CPlayer player2(30, 30);
while(!ezKeyHit(27)) // Main Loop
{
ezCls();
player1.draw();
player2.draw();
ezFlip();
}
}
Thanks
