The "How do I..." Thread

[ThatOneZDoomer]

How do I make a melee weapon that has several different animations and attacks when I press fire? Like, say, if I had four, there would be a 25% chance each would be called, so that when I press fire, it randomly does one of several of these attacks. Anyone?

That should be simple to do. As an example...

Code: Select all

Actor MultiFist : Fist
{
	States
	{
	Fire:
		PUNG A 0 A_Jump(256,"Punch1","Punch2","Punch3","Punch4") //This should give an equal chance of jumping to any of the four states below.
	Punch1:
		PUNG B 4
		PUNG C 4 A_Punch
		PUNG D 5
		PUNG C 4
		PUNG B 5 A_ReFire
		Goto Ready
	Punch2:
		PUNG B 4
		PUNG C 4 A_Punch
		PUNG D 5
		PUNG C 4
		PUNG B 5 A_ReFire
		Goto Ready
	Punch3:
		PUNG B 4
		PUNG C 4 A_Punch
		PUNG D 5
		PUNG C 4
		PUNG B 5 A_ReFire
		Goto Ready
	Punch4:
		PUNG B 4
		PUNG C 4 A_Punch
		PUNG D 5
		PUNG C 4
		PUNG B 5 A_ReFire
		Goto Ready
	}
}

I haven't actually tested that particular example, but it should work, since I did something similar with having a rail gun that randomly fires different colored shots anytime you shoot.

I used that method to give my minigun more than one kind of flash.

Thanks, ZDoomer. One question, though: What does the "256" represent?

Thanks, ZDoomer. One question, though: What does the "256" represent?

It is the numerical probability that the Jump Command will occur. The maximum number is 256, so a value of 256 means the Jump Command always happens.

[Ceeb]

Thanks, ZDoomer. One question, though: What does the "256" represent?

The number is the odds of a jump. 0 is never, 256 is always.

2) DynamiteTID should be the TID of the dynamite, so in the dynamite, put something like Thing_ChangeTID(0,134), and use 134 instead of DynamiteTID. Unless you'll be able to chuck many more dynamites faster, then I think you'll have to use a script that changes each dynamites actors TID separately.

3) Compile it? (You should have a lump above it named whatever you want, and you can also change it's type to 18 - which makes it an ACS lump. SCRIPTS lumps always compile to the lump above. Keep that in mind.)

2) Well, you can chuck dynamites pretty fast, because you can throw it like a turd and then you don't really need to hold the button.

3) I don't understand you there. I have the ACC compiler, but when I dragged an ACS file onto the compiler, I recieved a .o file, so I put that into my .wad, put in a LOADACS lump, put 'DYNSCRI' in there, but it said 'unknown p-code 347 in script 128'! What am I doing wrong?

Also, how do I convert the compiled ACS script to a script that you can edit? And what do I have to replace with HOLDTIME?

[Ryan Cordell]

XWE allows you to search for the compiler, so you can just click on a SCRIPTS lump and compile it from there. And just a wild guess..

Did you also have #include "zcommon.acs" at the top?

@Ceeb: Shouldn't it be 255 more like it though? I don't trust 256 anymore, especially when you consider it's an overflow in the Turbo function (max. is 255) and in the Painchance property (256 becomes -1, as far as the engine is concerned.), might be elsewhere too.

Got the p-script thing to work (I use Skulltag 97e from now), but the strength doesn't work at all. Neither does the bar show up.

Seems quite arbitrary. 256? Why not 100 to represent percentage? It would be much simpler (in the case of multi-choice arguments) to do this so you could have, say for four arguments with equal probability, set each one to 25. 256 is confusing as hell and I don't even know if the math would work on that without any preconceived concepts of how it works..

[Ceeb]

Quit your fucking bitching and take it up with randy if you really care THAT much about something so utterly pointless.

And yes, I'm in a foul mood.

256 is 2*128, 4*64, 8*32, 16*16. So a quarter of 256 is 64, an eighth is 32. Three quarters is 192 (64*3).

Like 100, 256 is a perfect square... 100 is 10^2, 256 is 16^2. But 256 is also 4^4 and 2^8. It's a perfect 4th power and perfect 8th power as well, making it inherently cooler than 100. Does that help?

You did that just to spite me.

Sorry, but I have another problem...

I'm working on a HUD.



When I load it up, it does that... clipping thing in the blank area. How do I fix this? I've tried a few things that I know of, but it still does that.
