Hi I was creating a simple ball movement for one of my games, and as I was typing it out, the maths part of my brain was screaming at me "Hey there is a formula here your doing all this typing for nothing", and I couldn't put my finger on what the formula was. i was wondering if anyone could help me?
Code:void Ball::collisionWindowTest() { // See if ball is about to leave the play area from top if (itsY == 0) { // Switch the direction value switch (itsDirection) { // Direction is equal to up case (0): { itsDirection = 4; break; } // Direction is up and right case (1): { itsDirection = 3; break; } // Direction is up and left case (7): { itsDirection = 5; break; } default: break; } } // See if ball is about to leave the play area from bottom if (itsY == 448) { // Switch the direction value switch (itsDirection) { // Coming in from the bottom right case (3): { itsDirection = 1; break; } // Coming in from the bottom case (4): { itsDirection = 0; break; } // coming in from the bottom left case (5): { itsDirection = 7; } } } // See if the ball is about to leave the play area from left if (itsX == 0) { // Switch the directon value switch (itsDirection) { // coming in from the bottom left case (5): { itsDirection = 3; break; } // coming in from the left case (6): { itsDirection = 2; break; } // coming in from top left case (7): { itsDirection = 1; break; } } } // See if the ball is about to leave the play area from right if (itsX == 608) { // Switch teh direction value switch (itsDirection) { // leaving top right case (1): { itsDirection = 7; break; } // Leaving right case (2): { itsDirection = 6; break; } // Leaving bottom right case (3): { itsDirection = 5; break; } } } }
