Modding:Mutations
Revision as of 17:13, 21 May 2019 by imported>CaptainTechnicality54384 (Created page with "Category:Modding First, include a mutations.xml in your mod that defines a new mutation. Mutations.xml sample, adding a simple mod <?xml version="1.0" encoding="utf-8"...")
First, include a mutations.xml in your mod that defines a new mutation. Mutations.xml sample, adding a simple mod
<?xml version="1.0" encoding="utf-8" ?>
<mutations>
<category Name="Physical">
<mutation Name="Udder" Cost="1" MaxSelected="1" Class="FreeholdTutorial_Udder" Exclusions="" Code="ea"></mutation>
</category>
</mutations>
Then add a new .cs file in your mod that implements the class. Here's a skeletal implementation of the entry above. It must be in the XRL.World.Parts.Mutation namespace and must ultimately descend from BaseMutation. (Though not necessarily directly, if you have a very complex mod)
Skeletal mutation example.

Your namespace should be XRL.World.Parts.Mutations, the class should be marked serializeable and derived from BaseMutation.
using System;
using System.Collections.Generic;
using XRL.UI;
using ConsoleLib.Console;
namespace XRL.World.Parts.Mutation
{
[Serializable]
class FlamingHands : BaseMutation
{
GetDescription and GetLevelText are called to generate the descriptive for a given level of the mutation.
public override string GetDescription()
{
return "You emit jets of flame from your hands.";
}
public override string GetLevelText(int Level)
{
string Ret = "Emits a 9-square ray of flame in the direction of your choice\n";
Ret += "Cooldown: 10 rounds\n";
Ret += "Damage: " + Level + "d6\n";
Ret += "Cannot wear gloves";
return Ret;
}
Change level is called any time the mutation changes level.
public override bool ChangeLevel(int NewLevel)
{
Physics pPhysics = ParentObject.GetPart("Physics") as Physics;
TemperatureOnHit pTemp = FlamesObject.GetPart("TemperatureOnHit") as TemperatureOnHit;
pTemp.Amount = (Level*2) + "d8";
return base.ChangeLevel(NewLevel);
}
Mutate and Unmutate are called on an object when it gains or loses the mutation.
public override bool Mutate(GameObject GO, int Level) public override bool Unmutate(GameObject GO)
BaseMutation derives from Part, so the typical event registration and handling functions are available
public override void Register(GameObject Object) public override bool FireEvent(Event E)
