Hello,

I am Brian Washechek, a 28 year old student at Casper College. Please look at this game! It's Force Disruptor 2, a sequel to a game i wrote a long, long time ago (i'm thinking like 7 years). I'll keep on attempting to write code for this if you would take a look at it! Basicly the walls only display (no hit detection) and i can't get it right! This is a sequel to Force Disruptor (the original), that got lost a long time ago. Seriously, Thank you for the help

Code:bool intersectionOfLines(double x1, double y1, double x2, double y2, double x3, double y3, double x4, double y4, double *x, double *y) { double Ax,Bx,Cx,Ay,By,Cy,d,e,f,num,offset; short x1lo,x1hi,y1lo,y1hi; Ax = x2-x1; Bx = x3-x4; if(Ax<0) { x1lo=(short)x2; x1hi=(short)x1; } else { x1hi=(short)x2; x1lo=(short)x1; } if(Bx>0) { if(x1hi < (short)x4 || (short)x3 < x1lo) return false; } else { if(x1hi < (short)x3 || (short)x4 < x1lo) return false; } Ay = y2-y1; By = y3-y4; if(Ay<0) { y1lo=(short)y2; y1hi=(short)y1; } else { y1hi=(short)y2; y1lo=(short)y1; } if(By>0) { if(y1hi < (short)y4 || (short)y3 < y1lo) return false; } else { if(y1hi < (short)y3 || (short)y4 < y1lo) return false; } Cx = x1-x3; Cy = y1-y3; d = By*Cx - Bx*Cy; f = Ay*Bx - Ax*By; if(f>0) { if(d<0 || d>f) return false; } else { if(d>0 || d<f) return false; } e = Ax*Cy - Ay*Cx; if(f>0) { if(e<0 || e>f) return false; } else { if(e>0 || e<f) return false; } //compute intersection coordinates if(f==0) return false; num = d*Ax; offset = SAME_SIGNS(num,f) ? f/2 : -f/2; *x = x1 + (num+offset) / f; num = d*Ay; offset = SAME_SIGNS(num,f) ? f/2 : -f/2; *y = y1 + (num+offset) / f; return true; } //....................later in the c++ file................................... if (intersectionOfLines( FDX-cos(FDA)+0, FDY-sin(FDA)+9, FDX+cos(FDA)+1, FDY+sin(FDA)+.8, wallX[i]-cos(wallRot[i])*wallRot[i], wallY[i]-sin(wallRot[i])*wallRot[i], wallX[i]-cos(wallRot[i])*wallRot[i], wallY[i]-sin(wallRot[i])*wallRot[i], &FDX,&FDY)) { bigX = true; // A collision occured, but for now it gets a BIG X... }
