Title: help with custom action for ship route
Post by: santelia on July 11, 2012, 07:02:07 AM

Here's our first try to create a custom action.
Created with custom action tool, assigned to Math category, then filled with the code in MonoDevelop and saved.
But when finally we put it in a state, it shows up completely empty  :(
Surely we forgot something...
Any help, including process?

Here is the code

Code: [Select]

using UnityEngine;
using HutongGames.PlayMaker;

[ActionCategory(ActionCategory.Math)]
[Tooltip("gets point along a circle for naval route purposes")]
public class FloatCircleCalculate : FsmStateAction
{
// distance from target point
[RequiredField]
[UIHint(UIHint.Variable)]
public FsmFloat distanzaPuntoTarget;

// target point

public FsmVector3 posizionePuntoTarget;

// ship point

public FsmVector3 posizioneNave;

// angle between ship and X

public FsmFloat angoloNaveSuX;

// angle between ship and target point

public FsmFloat angoloNaveSuTarget;

// temporary point of route

public FsmVector3 puntoDiRotta;

// check box for every frame

public bool everyFrame;

// Code that runs on entering the state.
public override void OnEnter()
{
if (angoloNaveSuTarget.Value != 0) {
puntoDiRotta.Value.x = posizioneNave.Value.x+distanzaPuntoTarget.Value*Mathf.Cos(angoloNaveSuX.Value*Mathf.PI/180);
puntoDiRotta.Value.z = posizioneNave.Value.z+distanzaPuntoTarget.Value*Mathf.Sin(angoloNaveSuX.Value*Mathf.PI/180);
}

if (!everyFrame)
Finish();

}

// Code that runs every frame.
public override void OnUpdate()
{
if (angoloNaveSuTarget.Value != 0) {
puntoDiRotta.Value.x = posizioneNave.Value.x+distanzaPuntoTarget.Value*Mathf.Cos(angoloNaveSuX.Value*Mathf.PI/180);
puntoDiRotta.Value.z = posizioneNave.Value.z+distanzaPuntoTarget.Value*Mathf.Sin(angoloNaveSuX.Value*Mathf.PI/180);
}

}


}

Hi,

 Ok, here is a corrected version of this action.

1: notice that I am using the hutongs namespace, not sure if it play a role, but I always built actions like that.
2: you had an c# error, you cannot set the components of a vector without making it first as a variable
3: I removed redundant code, so now it's cleaner and easier to maintain.

Code: [Select]

// (c) Copyright HutongGames, LLC 2010-2012. All rights reserved.

using UnityEngine;

namespace HutongGames.PlayMaker.Actions
{
[ActionCategory(ActionCategory.Math)]
[Tooltip("gets point along a circle for naval route purposes")]
public class FloatCircleCalculate : FsmStateAction
{
// distance from target point
[RequiredField]
[UIHint(UIHint.Variable)]
public FsmFloat distanzaPuntoTarget;

// target point

public FsmVector3 posizionePuntoTarget;

// ship point

public FsmVector3 posizioneNave;

// angle between ship and X

public FsmFloat angoloNaveSuX;

// angle between ship and target point

public FsmFloat angoloNaveSuTarget;

// temporary point of route

public FsmVector3 puntoDiRotta;

// check box for every frame

public bool everyFrame;

// Code that runs on entering the state.
public override void OnEnter()
{
computePoint();

if (!everyFrame)
{
Finish();
}
}

// Code that runs every frame.
public override void OnUpdate()
{
computePoint();

}

private void computePoint()
{
if (angoloNaveSuTarget.Value != 0) {
Vector3 _puntoDiRotta = puntoDiRotta.Value;

_puntoDiRotta.x = posizioneNave.Value.x+distanzaPuntoTarget.Value*Mathf.Cos(angoloNaveSuX.Value*Mathf.PI/180);
_puntoDiRotta.z = posizioneNave.Value.z+distanzaPuntoTarget.Value*Mathf.Sin(angoloNaveSuX.Value*Mathf.PI/180);

puntoDiRotta.Value = _puntoDiRotta;

}
}


}
}


 Bye,

Again, thank you Jean.
Also, what exactly have I to do to add it at the playmaker actions without breaking any data base (or whatever) integrity? I mean, copy the code, open a new action in MonoDevelop, paste and save it with the right name under "actions" folder, or what else?

Hi,

 nothing else, it just scan the project folder or something. You are not going to break anything, unless you create an action that exists already ( clashing class names), bu you will get an error in Unity console anyway.

bye,
