[FFC] eSword

Now, you can make an enemy that actually holds a weapon instead of trying to randomly run into you!


//eSword.z, written by Raiu aka dragonsword aka N8Read
//makes an enemy and has it hold a weapon IF screen->D0 is 0
//arguments: 0=which enemy, 1=x, 2=y. 3=how many pixels ahead of enemy, 4=sprite to use for weapon, 5=how much damage in quarter hearts, 6=delay before forming new if hit something

What it does: creates an enemy on the screen and makes it wield a sword!
the enemy will always re-appear whenever you re-enter the screen unless another script sets Screen->D[0] to something besides 0.

Arguments:
D0: ID of the enemy
D1: starting X position
D2: starting Y position
D3: How many pixels ahead of the enemy the sword is. (11-14 are good numbers)
D4: ID of the sprite to use
D5: damage the weapon does in quarter hearts
D6: how many frames the enemy waits before re-stabbing the sword if it hit something
