Modding Help Scorpion Spear

Got an idea to learn how to make either a weapon that shoots projectiles, or a thrown weapon. I decided I wanted to recreate the infamous 'get over here' spear from Mortal Kombat used by Scorpion. I'm at this point so far, but it comes up as a Perfectly Generic Item.

scorpionspear.thrownitem

Code:

{
  "itemName" : "scorpionspear",
  "rarity" : "Common",
  "inventoryIcon" : "scorpionspearicon.png",
  "image" : "scorpionspear.png",
  "shortdescription" : "The "Get Over Here" Spear",
  "description" : "Get Over Here!",

  "ammoUsage" : 1,

  "edgeTrigger" : true,
  "windupTime" : 0.0,
  "cooldown" : 0.4,

  "projectileType" : "scorpionspearprojectile",
  "projectileConfig" : {
    "speed" : 70,
    "power" : 100
  }
}

scorpionspearprojectile.projectile

Code:

{
  "projectileName" : "scorpionspearprojectile",
  "frames" : scorpionspear.png",
  "animationCycle" : 0.5,
  "level" : 3,
  "frameNumber" : 4,
  "power" : 50,

  "lightColor" : [255, 180, 0],
  "damageKind" : "slash"
}

scorpionspearprojectile.frames

Code:

{
  "frameGrid" : {
    "size" : [190, 24],
    "dimensions" : [4, 1],

    "names" : [
      [ "0", "1", "2", "3" ]
    ]
  }
}

Also, here are the .png files I've created for it

scorpionspearprojectile.png



scorpionspearicon.png



scorpionspear.png



I'm pretty sure it has to do with the frames, as I have no clue on how to set parameters to tell the game what pixels to grab or whatever, I'm clueless!

Edit 1: Updated scorpionspearprojectile.frames code to "frames" : scorpionspear.png,"

Edit 2: Updated scorpionspearprojectile.png so they are in a row.

Edit 3: Edited scorpionspearprojectile.frames

 

Lol this is a cool idea. though i dont know if i want some of those monsters to be that close they are after all a huge pain in the butt to begin with usually.

 

Download link?

 

Question:Mods working in multiplayer?

 

It's not working yet, it's coming up as a perfectly generic item. I am like the dog sitting at the computer right now. I have no idea what I'm doing.


Edit: If someone more proficient than me can figure it out, you can take all of the assets I've posted. I just want to learn how to mod =P.

 

" "frames" : "scorpionspearprojectile.frames","

looks like that should be scorpionspearprojectile.png

Or whatever the png is called

 

Also, the .png might be set up wrong. I'd suggest putting each image all in a row so ---> -~~> ~~~> or whatever.

Then you need to fix your .frames file.

"size" : [16, 16], - This means that each frame in the sprite sheet is 16px by 16px (x by y).
"dimensions" : [8, 1], - This means that there are 8 frames on the x axis and only 1 row of frames in the sprite sheet.
These numbers are just examples, you'll have to figure out yours.

Edit: a frame is a single image from the animation. You have 4 frames.

 

Updated the .frames file to this...

Code:

{
  "frameGrid" : {
    "size" : [190, 24],
    "dimensions" : [4, 1],

    "names" : [
      [ "0", "1", "2", "3" ]
    ]
  }
}

 

That looks good to me. Did you change where you had .frames to .png?

 

Getting this error from the starbound.log

I got the game to run again, I commented out the damageKind and LightColor variables in the scorpionspearprojectile.projectile file. I put those back in. Game boots, but found this error

EDIT: Update, Got the item in my game finally, realized the description had a quotation mark in it, that was keeping the asset from loading. The item loads, now the problem is I try throwing it and the game crashes >.<.

 

Update: Got it to work in game, and damage. Turns out I didnt need to add .png to "projectileType" : "scorpionspearprojectile", after all. Now I'm tweaking it to make it look half way decent. Also, I'd like to add sound effects. Just don't know how.

Also, the animation cycle is all bonkers, it goes from the first frame to the last, over and over, and also switches the positions of each frame over and over.

 

Playing a sound should be pretty simple, look at some other things that play a sound when they're activated, they would normally call a lua or config file from actionOnReap. As for your animation not working, I'm not quite sure what to say. The images are really quite similar, are you sure it's actually skipping the middle two?

 

I'm not sure I follow, here is what I have so far. Loads item, etc. doesn't work.

Code:

"firesound" :  { "mk_harpoon" : [ { "file" : "/sfx/projectiles/mk_harpoon.wav" } ] }

Not sure about how to find the config files for sfx or make one.

Also, could it be because I'm using a throwing item config file?

 

a good example on how to play a sound from a projectile is the explosivebullet.projectile:

Code:

{
  "projectileName" : "explosivebullet",
  "frames" : "explosivebullet.png",
  "animationCycle" : 0.25,
  "armorPenetration" : 3,
  "frameNumber" : 1,
  "energyCostPerDamagePoint" : 25,
  "damageKindImage" : "icon.png",
  "pointLight" : false,
  "actionOnReap" : [
    {
      "action" : "config",
      "file" : "/projectiles/explosions/vsmallregularexplosion/vsmallregularexplosion.config"
    }
  ],
  "power" : 5.0,
  "damageType" : "hitTest",
  "damageKind" : "default"
}

if you look at the actionOnReap, it calls an action called config and puts the absolute path to vsmallregularexplosion.config
If we go to that config file we see this:

Code:

{
  "action" : "actions",
  "list" : [
    {
      "action" : "projectile",
      "inheritDamageFactor" : 1,
      "type" : "vsmallregularexplosion"
    },
    {
      "action" : "loop",
      "count" : 10,
      "body" : [
        {
          "action" : "spark"
        }
      ]
    },
    {
      "action" : "sound",
      "options" : [ "/sfx/gun/grenadeblast1.wav", "/sfx/gun/grenadeblast2.wav", "/sfx/gun/grenadeblast3.wav" ]
    },
    {
      "action" : "light",
      "color" : "orange"
    },
    {
      "action" : "explosion",
      "foregroundRadius" : 1,
      "backgroundRadius" : 0,
      "explosiveDamageAmount" : 0.5,
      "delaySteps" : 2
    }

  ]
}

There's lots of things you can do we the config. You can set more actions for the projectile (animations could go here too), if you wanted it to choose 1 sound out of three you could do that here too.
The part you're looking at is similar to the action: config part of the previous page. It says "action" : "sound" when this action is triggered (which will be when the projectile is activated) it will play one of those sounds (.wav).

There are lots of free open source sounds on the internet that you can use, if they're not in .wav, find a program to convert them. I use Audacity (because free is always better). With audacity you can also record your own sounds.

 

Actually, you could probably put the action from the config into the .projectile action area and skip the whole second part

 

scoprionspearprojectile.config

Code:

{
      "action" : "sound",
      "options" : [ "sfx/projectiles/mk_harpoon.wav" ]
    }

    

scorpionspearprojectile.thrownitem

Code:

{
  "itemName" : "scorpionspear",
  "rarity" : "Common",
  "inventoryIcon" : "scorpionspearicon.png",
  "image" : "scorpionspear.png",
  "shortdescription" : "The Get Over Here Spear",
  "description" : "Get Over Here!",

  "ammoUsage" : 0,

  "edgeTrigger" : false,
  "windupTime" : 0.1,
  "cooldown" : 1.0,

  "projectileType" : "scorpionspearprojectile",
  "projectileConfig" : {
    "speed" : 75,
    "power" : 9001,

"actionOnReap" : [
    {
      "action" : "config",
      "file" : "/projectiles/scorpionspearprojectile.config"
    }
  ]
   
}

}

New problem, when it tries to play the .wav file, the game crashes, and it didn't crash when it played the explosive bullet effect and sound.

 

is your .wav saved in the proper folder?

Edit: sfx should be in the assets (or mods) directory. Put a / in front of it just to be safe

 

Code:

{
"action" : "sound",
"options" : [ "sfx/projectiles/mk_harpoon.wav" ]
}

This is your problem,
This: "options" : [ "sfx/projectiles/mk_harpoon.wav" ]
Should be this: "options" : [ "/sfx/projectiles/mk_harpoon.wav" ]

 

Oh, lmao thanks a lot I'm laughing right now how dumb I am.

And it still crashes the game. Yes, the .wav file is in the proper folder.

Oh, and I'd also like to know if there is a command to 'activate a sound on use', the sound seems to only be activating when it hits an object.
