I've been working with Zscript for quite a while now, but the one thing that I just can't wrap my head around is eweapons and lweapons.

When I look through other people's code I see a whole bunch of tasks dedicated to making a single weapon appear. It's all so confusing and big that I can't learn properly from those. I just want to make simple weapons and special effects (like sparks) with lweapons and eweapons that disappear after x frames, but there's no clear to understand documentation on how to do that.

 

 

Does someone have a tutorial on how to use them properly and without too much confusion?

Well, what exactly are you trying to do? I don't know about you, but I like to learn by doing.

I wrote http://www.purezc.ne...showtopic=59398 recently, which is what I think you want. Here's the code in the example quest, for reference:

import "std.zh"
import "animation.zh"
import "stdExtra.zh"
import "ffcscript.zh"
 
// Make a constant for the sprite id.
const int SPRITE_PRETTY = 88;
 
global script Active {
  void run() {
 
    // Make a main pretty that stays forever (the true keeps it forever).
    lweapon mainPretty = AnimationCreate(SPRITE_PRETTY, 0, 0, true);
 
    // Grab the id so you can use it after you call Waitframe().
    int mainId = AnimationGetId(mainPretty);
 
    while (true) {
 
      lweapon animation;
 
      // Move the main pretty to link if L is pressed.
      if (Link->PressL) {
        // Get the animation back from the id.
        animation = AnimationGet(mainId);
 
        // And then move it to link.
        animation->X = Link->X;
        animation->Y = Link->Y;}
 
      // Shoot out 3 pretties if R is held.
      if (Link->InputR) {
        for (int i = 0; i < 3; i++) {
          // No true at the end means it only lasts through 1 cycle of the animation.
          animation = AnimationCreate(SPRITE_PRETTY, Link->X, Link->Y);
          // Since we're not touching it after we create it, we don't need to grab
          // the id, either.
 
          // You can set up its movement just like it was a regular weapon, but
          // you don't need to worry about it falling off the edge.
          animation->Angular = true;
          animation->Step = Rand(50,200);
          animation->Angle = Rand(PI2);}}
      
      // This makes it so that the R button animations actually move.
      AnimationUpdate();
 
 
      Waitframe();}}}

 
Basically, you just call AnimationUpdate() in your main loop, and then create an animation with lweapon animation = AnimationCreate(sprite_id, x, y). You can assign the animation movement just like a regular weapon and then forget about it.

By default it makes the animations last for 1 run through the sprite. You can assign to animation->DeadState the number of frames you want it to last after you make it if you want different behavior.

Thanks grayswandir and Soga, those helped me a lot. Now I finally understand what I'm doing and managed to make a custom enemy weapon. (Deadstate works in a strange way)
