I'm trying to figure out where most of the slowdown is coming from in my code, and I noticed that there's a whole lot of unnecessary looping going on, even though it's not doing any processing during it.

Basically, would this be a significant source of slowdown if most of the EnemyStructArray was empty?

void Enemies(){

  for(x=0;x<100;x++){

    switch(EnemyStructArray[x].ID){

    case 0:

    case 1: A;

            Hundred;

            Lines;

            Of;

            Code;

    }

  }

}

And if so, would this be faster?

void Enemies(){

  for(x=0;x<100;x++){

    switch(EnemyStructArray[x].ID){

    case 0:

    case 1: Enemy1AI(x);

    }

  }

}



void Enemy1AI(int EnemyStructArraySlot){

  A;

  Hundred;

  Lines;

  Of;

  Code;

}

It would not, however, be a significant slowdown. I do recommend you pulling something like that in it's own function, just for your sanity's sake.

TimeWizard: You could save a lot of time by keeping a count of how many enemies you have currently and doing something like:

void ProcessEnemies()

{

	for (i = 0; i < enemy_count; i++)

	{

		switch(enemy[i].id)

		{

			case 1:

				// Sneaky amateur ninja.

				EnemyMove(i, MOVE_CAUTIOUS);

				if (PlayerInEnemyRange(i))

				{

					EnemyAttackPlayer(i);

				}

			case 2:

				// Cowardly Idiot.

				EnemyMove(i, MOVE_RANDOM);

				if (PlayerInEnemyRange(i))

				{

					EnemyEvadePlayer(i);

				}

		}

	}

}

Note how I didn't include case 0, since I assume your case 0 does nothing. I'm making lots of assumptions, but hopefully good suggestions. Break the hundred lines of code into smaller functions that handle specific aspects of the enemy, especially if your enemies might share similarities with other enemies. This helps break down repetition, and it also makes one tweak to a function affect many enemies instead of having to redo each of them every time you want to change something to do with their movement and actions and etc.

Oh, is this action-game AI, not RPG?

Yeah, it's a platformer.

A Castlevania game to be specific. In the unlikely event Konami actually cares and I get crap about it, I'll just call it Transylpalace or some BS like that.
