Creature Attacks

The creatures in the game include a goblin, a snake, a wizard, and a dragon. The creature attacks are all located in a single function, and the attack initiated depends on the level you are on. The attacks happen   on a clock schedule.

void creatureAttack()
{
  float miss;
  float hit;
  
  passedAttackTime = millis() - savedAttackTime;
  
  if (passedAttackTime > totalAttackTime)
  …

Let's look at the goblin attack on level 1:

if (level == 1)
  {
   enemySound = minim.loadFile("SWORD.wav");
   miss = random(1,10);
   if (miss < 7)
   { 
     hit = random(5,15);
     damage = round(hit);
     hp -= damage;
     fill(255,0,0,40);
     stroke(255,0,0,40);
     rect(0,0,width,height);
     if (!attaText)
     {
      attaText = !attaText; 
     }
  }
  else
  {
     fill(255,0,0,10);
     stroke(255,0,0,10);

     rect(0,0,width,height);
     if (!missText)
     {
      missText = !missText; 
     }
  }
 }

The goblin attacks with an axe, so a 'sword' sound effect is used to represent a goblin attack. Then, a random number determines whether the goblin actually hits or misses the player. The goblin thus has a 30% chance of missing.

If the goblin hits you, a random number is generated between 5 and 15.

The round command will round the number to an integer, so you can't lose 7.33423521 HP. The damage then be deducted from the player HP.

Finally, a transparent red light will fill the screen, to represent the hit, and a boolean is set to display text in a later function. If the goblin misses, the red light is even more transparent, and a different boolean is set.

Now, let's look at the snake attack.

 else if (level == 2)
 {
   miss = random(1,10);
    enemySound = minim.loadFile("SNAKE.wav");
   if (miss < 9)
  { 
     hit = random(8,25);
     damage = round(hit);
     hp -= damage * playerResistanceP;
     fill(255,0,0,40);
     stroke(255,0,0,40);

     rect(0,0,width,height);
     if (!attaText)
     {
      attaText = !attaText; 
     }
  }


It looks identical to the goblin attack, just with different variables (more damage, less chance of missing). However, notice that hp is deducted by damage * playerResistanceP, so if a poison shield is generated (setting your wand to cast poison), it cuts the blow into half of the generated damage.
