Linked Lists

Hey, I am making a asteroids clone and I have a class called "Bullet." Right now I have it so that when you click the space bar, the "Ship" class calls the "Bullet::CreateBullet." The only problem is that when It tries to add the bullet to the linked list it crashes. Here is some of the code. // This function creates a bullet dynamically. I am I using the 'new' command correctly? void Bullet::CreateBullet(float x, float y, int Direction) { Bullet *NewBullet; NewBullet = new Bullet;// This calls the constructor correct? // Set the bullets properties NewBullet->SetPosition(x,y); NewBullet->SetObjectState(ALIVE); NewBullet->SetBulletVelocity(Direction); NewBullet->SetSize(4, 4); NewBullet->SetAnimationProperties(8, 8, 1, 1, DDSCAPS_SYSTEMMEMORY, "Data\\Art\\Weapons\\bullet"); NewBullet->SetFrame(1); } // The class Bullet's constructor adds bullet to linked list Bullet() { Type = BULLET; Damage = 5; DistanceFlown = 0; // Add to linked List if( pBulletFirst == 0 ) { // this is the first node pBulletFirst = this; pBulletPrev = NULL; } else { pBulletLast->pBulletNext = this; this->pBulletPrev = pBulletLast; } pBulletLast = this; this->pBulletNext = NULL; } Well, I think the problem is in the constructor, but maybe I am using the 'new' thing wrong. I have never used it before. Well thanks a lot guys. Later. Edited by - JSCFaith on May 12, 2001 7:37:36 PM
