I'll check this out when I get home, but just coded up a gun script.
Code:// =================================== // gun - This FFC will act as a gun. The user // specifies which direction the gun will fire. When // the player is lined up with the proper direction, // the gun will briefly switch to the next combo. // It will move the projectile FFC to its location, and // send it outwards in the proper direction. Projectiles will // be blocked by solid combos on layer 0. // D0 = delay between shots. // D1 = FFC number of the projectile combo // D2 = speed of the projectile // D3 = 1 if the gun can shoot north // D4 = 1 if the gun can shoot south // D5 = 1 if the gun can shoot east // D6 = 1 if the gun can shoot west // D7 = 1 if the gun is omnidirectional (meaning it will // fire at angles, regardless of where the player is.) // NOTE - If you make the projectile move too fast, it may zip off // of the screen before the script can save it. Keep the speed under // 16 to prevent this. // ========================================== ffc script gun{ void run(int shot_delay, int projectile_ffc_number, int projectile_speed, int shoots_north, int shoots_south, int shoots_east, int shoots_west, int omnidirectional){ int gun_state = 0; // 0 = primed and waiting for the player to come in range. // 1 = firing // 2 = waiting int firing_delay = 20; // Hard-coded delay while gun animation plays. Counter for state 1. int delay_counter = shot_delay; // Counter for state 2. int side_A; int side_B; int side_C; // Used to calculate the angle in an omnidirectional gun. projectile = ffc Screen->LoadFFC(projectile_ffc_number); while (true){ if (gun_state == 0){ if ( (shoots_north == 1) && (Link->X < this->X+16) && (Link->X > this->X-1) && (Link->Y < this->Y)){ projectile->X = this->X; projectile->Y = this->Y; projectile->Vy = -projectile_speed; projectile->Vx = 0; gun_state = 1; this->Data++; } if ( (shoots_south == 1) && (Link->X < this->X+16) && (Link->X > this->X-1) && (Link->Y > this->Y)){ projectile->X = this->X; projectile->Y = this->Y; projectile->Vy = projectile_speed; projectile->Vx = 0; gun_state = 1; this->Data++; } if ( (shoots_east == 1) && (Link->Y < this->Y+16) && (Link->Y > this->Y-1) && (Link->X > this->X)){ projectile->X = this->X; projectile->Y = this->Y; projectile->Vx = projectile_speed; projectile->Vy = 0; gun_state = 1; this->Data++; } if ( (shoots_west == 1) && (Link->Y < this->Y+16) && (Link->Y > this->Y-1) && (Link->X < this->X)){ projectile->X = this->X; projectile->Y = this->Y; projectile->Vx = -projectile_speed; projectile->Vy = 0; gun_state = 1; this->Data++; } if(omnidirectional == 1){ // First, check to see if the player is linked up vertically with the gun.
