The "How do I..." Thread

[NeuralStunner]

Derp... Thanks NS.

There's that D word again. But you're welcome.

So now, I'm implementing my upgraded Doom weapons in Resource. The way I intend for this to work is that when you get an upgraded version, it takes away the original, and any originals you come across simply provide some ammo, without the player collecting that weapon. The dilemma? How do I make the weapon check if the player has an upgraded version of it, and change to an ammo-only version? I'm hoping to do this without ACS, but I can if necessary...

[Ceeb]

Another question, but a quick one I'm hoping someone can answer. Is it possible to user user vars with weapons? I've heard about problems with them and don't want to invest a few hours rewriting my weapons to find out it was for nothing.

[NeuralStunner]

Is it possible to user user vars with weapons?

It's possible, but they don't work quite right. You can use Args[], which affects the Player's - I can't think of many reasons to attach a special to a Player actor.

[Ceeb]

Well, what doesn't quite work right? I don't, say, have multiplayer in my mods, so... If that's the problem...

[NeuralStunner]

Well, what doesn't quite work right?

ZDoom gets confused whether you're trying to reference a var on the Weapon or on the owning Player.

[Ceeb]

Ah, crap. Guess I'll stick with inventory items.

[NeuralStunner]

Again, Args[] still work, they can be used in the same ways as User Vars.

[Ceeb]

Hm... Alright then. I'll try that.

[Ceeb]

Here's another one. Is it possible to add to a state jump in a jump function? What I mean is, it's legal to do this:

Code: Select all

TNT1 A 0
Goto NextState + 4

But when I try to do this...

Code: Select all

TNT1 A 0 A_Jump(128,"NextState" + 4)

or any variant thereof I simply get an error. Is there any way to do this?

[ChronoSeth]

Using the number of frames to skip ahead rather than the state to jump to, perhaps? (I don't remember if that can be used across multiple states though)

It can, but I need to go backwards.

[NeuralStunner]

Add another state label?

[Ceeb]

Add another state label?

Gwarh, this weapon is fucktardedly complex as it is. Although by that logic, I suppose one more state won't hurt. I'm off to the feature-suggestionmobile, however.

[Ceeb]

Here's another one. In my deathmatch map, there's traps you can activate (turrets and such) and I need to be sure that the player who runs the script gets credit for the kills. Can I even do this?
