I have an animated enemy (which moves around)

 

 

It's possible create a script to recreate the animation? The enemy uses 19 tiles

 

NOTE: It's only a walking enemy with no weapons/eweapons.

You want to what now? You can make it a combo, and do DrawCombo, or just make an ffc with those graphics, which would do the same. I don't comprehend your goal.

You can also make a sprite of it, and use it for weapons, or items.

With a script, it'd be possible to clone the tile of an npc to another object, based on both its tile, and its direction; but it may be a frame out of sync.

You can also do raw DrawTiles() to do it, but it's the more complicated approach.

There is no raw 'DrawSprite' in zscript, but maybe there should be. I've considered adding that, but it's not something with a direct allegro instruction. Allegro has what equates to 'DrawSprite()', but that's for bitmap effects, not ZC 'sprites'. (Allegro defines a 'sprite' as a bitmap, so if you see that term in the allegro docs, it means something entirely different to what ZC means by a 'sprite'.)

I prefer use a combo and do the DrawCombo function for the enemy animation

I still don;t comprehend what you want to accomplish. Please, give specific details on how you want to draw it, where, when, and why.

Do you just want to draw multiple fake enemies tot he screen? Do you want them to move? I have no clue what you want to do.

If you want to draw a combo, first make the combo, then you do:

Screen->DrawCombo(1, x_pos, y_pos, combo_id, 1, 1, cset, -1, -1, 0, 0, 0, frame, 0, true, 128)
 
In this instruction, 'frame' is the N^th frame of the combo animation.
 
If it's supposed to move around, then you use x_pos and y_pos to set its position on the screen.
 
Draws last for only one frame, so you'd put it in a loop (for, while), and set its position, and frame using timers, and movement instructions.
 
Drawn combos have no collision, but you can fake it: In fact, I made a header (DrawCollision.zh) to do exactly that. If you want engine collision, use an enemy. If you want easier scripted collision, use an lweapon, an eweapon, or an item.
 
This is completely untested, and just out of me head...
