ghost.zh - A header file for ghosted enemy scripts

[Saffith]

Hey, I'm actually updating it. How about that.

The biggest change this time is the __GH_ALWAYS_USE_NAME setting. If it's enabled, AutoGhost() will always read an enemy's name to get the script and combo number. Misc. attributes 11 and 12 will be free for other scripts to use.
The script and combo number both go after @ in the name. Order and spacing aren't important, and other characters are allowed afterward. Either of these will work:
Goriya (LttP, Green) [@Goriya_LttP, @25804]
Goriya (LttP, Green) @25804@Goriya_LttP
You have to provide the script name, but if you don't specify a combo, it'll default to GH_INVISIBLE_COMBO. This will work fine:
Armos @Armos_LttP

The downside to this is that enemy scripts can no longer assume misc. attribute 11 specifies the base combo. I don't think that was a common thing to do, anyway.

Other notable changes:
The files in the ghost_zh directory have been moved to a numbered subdirectory. This will allow multiple versions to coexist.
Ghost_TileWidth and Ghost_TileHeight should now be considered read-only. Ghost_SetSize() should be used to set them.
You can now control what constitutes a pit by editing the __IsPit() function in the main file.
There's also a __HaveAmulet() function, used to determine if enemies are visible when the "All Enemies Are Invisible" screen flag is used.
Weapons can now have fake Z movement, both individually and globally.
Added a new death animation, as well as constants to use as arguments to Ghost_DeathAnimation() and Ghost_Waitframe().

There haven't been any changes to global data, so this version should be compatible with existing saves using 2.7.x. Still, be careful.

You just made my day. Thanks Saffith.


edit: I use this meme way too much. XD
@Saffith
I am laughing so hard right now. Burt the Bashful anyone?

* GHD_SHRINK
* The enemy grows slightly and then shrinks away to nothing. This does not
* work with enemies that use additional combos.

[ZoriaRPG]

Nice one. Are you adding a backward-compatibility setting, as a constant for this?

const int GHOST_USE_ENEMY_NAMES_FOR_SCRIPTS = 1; 

if ( GHOST_USE_ENEMY_NAMES_FOR_SCRIPTS ) gohst_use_at_sign_routines();
else ghost_use_misc11_misc12();

Something like that would be good. Just set the constant in the main header file, and use it as needed. That will prevent conflicts with games that are built on the old system.

[Saffith]

__GH_ALWAYS_USE_NAME. It's disabled by default.

[ZoriaRPG]

__GH_ALWAYS_USE_NAME. It's disabled by default.

Gorgeous.

@Saffith

Have an issue with sideview shenanigans "Sideview Gravity ugh..."
So just ghost.zh take care of it on its' own as far Ghost_Z is concerned?

[Saffith]

What problem are you having?

Hm, I thought Ghost_Z affected ghost->Y in sideview, but it looks like it's not as consistent as it should be. It's likely to be a bit messy at best, but I could probably improve on it.

[Tamamo]

That may be my problem then.
I'm setting Ghost_Y to 160 each frame. "It's Barba"

example quest

Lot of issues here, best to turn on collision hitbox cheat and see for yourself what's happening. Should reproduce the battle in sideview perfectly, but it does not.

edit: Fixed!

@Saffith
I have a few suggestions.

GHF_NO_SHADOW
Unless there's a way to disable the shadow that I don't know of.

EWM_VEER_ANGLE
EWM_DRIFT_ANGLE
EWM_DRIFT_WAIT_ANGLE
Same as normal except they move towards an angle.

EWD_FIRETRAIL.
For the pyro in all of us.
