Chapter 17 ■ Enhancing Game Play: Creating a Scoring Engine, Adding Treasure and an Enemy Auto-Attack Engine Figure 17-51. Add bulletType to conditional if statement evaluation in shootProjectile() method, to shoot cream cheese Next we need to do the same conversion for the bulletType equals true value. This will signify use of Cream Cheese as a Projectile object type. Once we put these conditional if() structures into place, we’ll have one if() structure for each logical combination of takeSides and bulletType. The last two conditional if() structures should look like this: if(bulletType && !takeSides) { invinciBagel.iCheese.spriteFrame.setTranslateY(randomOffset); invinciBagel.iCheese.spriteFrame.setScaleX(-0.5); invinciBagel.iCheese.spriteFrame.setScaleY(0.5); bulletRange = -50; if(bulletOffset >= bulletRange) { bulletOffset-=4; invinciBagel.iCheese.spriteFrame.setTranslateX(bulletOffset); } else { shootBullet = false; } } if(bulletType && takeSides) { invinciBagel.iCheese.spriteFrame.setTranslateY(randomOffset); invinciBagel.iCheese.spriteFrame.setScaleX(0.5); invinciBagel.iCheese.spriteFrame.setScaleY(0.5); bulletRange = 624; if(bulletOffset
Chapter 17 ■ Enhancing Game Play: Creating a Scoring Engine, Adding Treasure and an Enemy Auto-Attack Engine Tweaking a Game: Fine-Tuning the User Experience Let’s take a moment and make a couple of adjustments to the code now that the auto-attack logic is working, to make sure that our game play is professional. Place the iBeagle, iBullet, and iCheese objects off-screen at game start-up, by changing the X and Y location parameters in each of these object’s constructor methods with negative X location values that are the same as (or greater than) the width of the sprite image asset, as can be seen in Figure 17-52. Figure 17-52. Modify X and Y parameters for all Enemy and Projectile constructor methods, to place them off-screen You also may have noticed that the Projectile objects are on top of the Enemy’s bazooka, so let’s change the z-index of the iBeagle object, so the projectiles come from behind the gun. To do this, put your .add() method call for the iBeagle after iBullet, and before iBagel, at the end of the .addGameActorNodes() method, as seen in Figure 17-53. Figure 17-53. Change z-index of iCheese and iBullet in the addGameActorNodes() method so they’re before iBeagle 446 www.it-ebooks.info
