Modding Help where is the action "water" defined?

I'm playing with custom projectiles and noticed the "lavaballoon" has an action of "water" and I can't for the life of me find where this is defined. How does the game know what "water" means? when I change it to any of the other named liquids the game crashes.

Code:

{
  "projectileName" : "lavaballoon",
  "physics" : "grenade",
  "frames" : "lavaballoon.png",
  "level" : 3,
  "animationCycle" : 0.5,
  "frameNumber" : 2,

  "actionOnReap" : [ { "action" : "water" } ],
  "damageKind" : "default"
}

 

The lava balloon is unfinished then I guess, since that will spawn water, not lava. To make it spawn lava, I think you'd do this:

Code:

{
"projectileName" : "lavaballoon",
"physics" : "grenade",
"frames" : "lavaballoon.png",
"level" : 3,
"animationCycle" : 0.5,
"frameNumber" : 2,

"actionOnReap" : [ { "action" : "water", "liquidId" : 3 } ],
"damageKind" : "default"
}

Where "liquidId" is taken from the "assets\liquids.config" file. The action should probably have been named "liquid" rather than "water" to avoid confusion, but there you go.

 

Thanks mate!!! works like a charm
