"How do I ZScript?"

Why do you feel the need to cheat with sprite names? Even when using just letters and numbers you have 1679616 distinct sprite names available.
There's just no need to add such hacks to the engine.

While I am not justifying kodi's hack attempt, the answer to that question is simple, really: for organizing and readability purposes, using long filenames is 100000x easier to work with than cryptic 4-letter abbreviations.

"human - caucasian - body - walking001 - 0.png" is much easier to identify than "HCBAA0.png". :P

Everything in the project is animated in 35 fps to allow walking-while-firing frames in a custom chase state, and also to govern frame duration for everything with A_SetTics and time factor lookup. Sprite names and frame numbers are chosen from an array each tick as well depending on a variable that represents where the character is in a particular frame cycle, so everything is primed for global or localized speeding up or slowing down of time.

TL;DR: lots of frames, lots of four letter words abbreviations. Nevermind the proposed hack, I'll manage with aspirin

Sorry, but the sprite system is not fixable without breaking it.

And breaking it certainly would not be fixing it, in the strictest sense of the word.

Sorry, I just had to put that in there... don't mind me... >_>

I didn't want to explicitly state the conundrum here...

If you really need long filenames you could use TEXTURES

Saving everything as sprite sheets and then parsing them with TEXTURES [EDIT: and realizing I can (a) add comments to my TEXTURES lump and (b) leave TEXTURES open in a background window that stays visible next to my working ZScript file] has been such a headache-saver for me...

Since I'm setting the sprites with zscript functions anyway, I'll be using some form of nicer name reference/lookup table or whatever.

It seems the projectile pitch doesn't change while flying, but only angle. So i want to know how to find projectile's momentum pitch in zscript?
I saw flag PITCHFROMMOMENTUM from modeldef, it actually find pitch of projectile, but how get that pitch in zscript?

Code: Select all

projectile.angle //works
projectile.pitch //equals to 0

Code: Select all

override void PostBeginPlay()
	{
		A_SetPitch(-atan2(vel.z,sqrt((vel.x*vel.x) + (vel.y*vel.y)))); 
		Super.PostBeginPlay(); 
	}

You can also use A_FaceMovementDirection, but it doesn't work in PostBeginPlay so is unusable for some particular things. Or at least was a few months ago.

OMG Big Thanks!!! I wanna say this is i do for collision code with CanCollideWith()
here PRE-Results:

with your pitch find algorythm, i think i can do precise collision of Sphere(basketball) with Circle(ring) in zscript!

p.s.:sry for img size, i thought i sent small size when i saw img post on discord(

Also how to find vector pitch from invoker actor to another actor?

How do I use random number in Damage property of projectile? When i put in 'random(1,10);', it returns error, that even numbers has to be used
