Problem with TD script (from java to c#)

Questions & Answers
1

Hi guys. I’m making Tower Defence game and i stuck in scrip which i translated from java to c#. I have 3 errors and i can’t solve them

  1. Assets/Skrypty/InGAmeGUI.cs(64,53): error CS0266: Cannot implicitly convert type UnityEngine.Object' to UnityEngine.GameObject’. An explicit conversion exists (are you missing a cast?)

  2. Assets/Skrypty/InGAmeGUI.cs(66,64): error CS1612: Cannot modify a value type return value of `UnityEngine.Transform.localEulerAngles’. Consider storing the value in a temporary variable

  3. Assets/Skrypty/InGAmeGUI.cs(95,25): error CS0103: The name `buildPanelTweener’ does not exist in the current context

    using UnityEngine;
    using System.Collections;

    public class InGAmeGUI : MonoBehaviour {

    //NGU items

public bool buildPanelOpen = false;
public TweenPosition BuildPanelTweener; 
public TweenRotation BuildPanelArrowTweener;

//Placement Plane Items
public Transform placementPlanesRoot; // attach the placement plane root
public Material hoverMat; // attach the hover material to this slot
public LayerMask placementLayerMask; // calls up the layer mask selection
private Material originalMat;
private GameObject lastHitObj;

//Build Selection Items
public Color onColor;
public Color offColor;
public GameObject[] allStructures;
public UISlicedSprite[] buildBtnGraphics;

private int structureIndex = 0;

void Start ()
{
	//reset the structure index, refresh the GUI
	structureIndex = 0;
	UpdateGUI();
}

void Update ()
{
	if ( buildPanelOpen )
	{
		 var ray = Camera.main.ScreenPointToRay ( Input.mousePosition );
		RaycastHit hit;
		if ( Physics.Raycast ( ray,out hit, 1000, placementLayerMask ) )
		{
			if ( lastHitObj )
			{
				lastHitObj.renderer.material = originalMat;
			}
			lastHitObj = hit.collider.gameObject;
			originalMat = lastHitObj.renderer.material;
			lastHitObj.renderer.material = hoverMat; // sets the planes material to the highlighted material
		}
		else // if the raycast didn’t hit anything
		{
			if ( lastHitObj ) // if we had previously hit something
			{
				lastHitObj.renderer.material = originalMat; // visually de select that object
				lastHitObj = null; // nullify the plane selection
			}
		}
		// drops a turrent on click
		if ( Input.GetMouseButtonDown(0) && lastHitObj ) //left mouse button was clicked and there is a last hitObject // if left mouse button (0) is clicked and we have something selected
		{
			if(lastHitObj.tag =="PlacementPlane_Open")
			{
				// drop the chosen structure exactly at the tile’s position and rotation of Zero. See how the “index” comes into play here?
				GameObject  newStructure = Instantiate( allStructures[structureIndex], lastHitObj.transform.position, Quaternion.identity );
				// set the new structure to have a random rotation. just for looks
				newStructure.transform.localEulerAngles.y = (Random.Range(0, 360));		//newStructure.transform.localEulerAngles.y = ( Random.Range ( 0, 360 ) );
				// set this tile’s tag to “Taken” so we can’t double place a structure
				lastHitObj.tag = "PlacementPlane_Taken";		
			}
		}
	}
}

void UpdateGUI () {

	//Go through all structure buttons (buttons in the build panel). and set them to “off”
	foreach(UISlicedSprite theBtnGraphic in buildBtnGraphics )//in buildBtnGraphics
	{
		theBtnGraphic.color = offColor;
	}
	//set the selected build button to “on”
	buildBtnGraphics[structureIndex].color = onColor;
}

// this happens whenever the build arrow is clicked
void ToggleBuildPanel ()
{
	if ( buildPanelOpen ) {
		// hide all build tiles
		foreach(Transform thePlane in placementPlanesRoot) 
		{
			thePlane.gameObject.renderer.enabled =false;
		}
		// plays the build panel tweener script backward ( false )
		buildPanelTweener.Play ( false );
		// sets the boolean to false ( closed )
		buildPanelOpen = false; 
	}
	

	else // the build panel was closed, so instead do this…
	{
		BuildPanelTweener.Play(true);
		BuildPanelArrowTweener.Play(true);
		foreach ( Transform thePlane in placementPlanesRoot )
		{
			thePlane.gameObject.renderer.enabled = true;
		}

	}
}
// Called whenever a structure choice is clicked ( the button in the build panel )
void SetBuildChoice ( GameObject btnObj )
{
	string btnName = btnObj.name;
	if ( btnName == "Btn_Farmer")
	{
		structureIndex = 0;
	}
	else if ( btnName == "Btn_Cow" )
	{
		structureIndex = 1;
	}
	else if ( btnName == "Btn_Alien")
	{
		structureIndex = 2;
	}
	UpdateGUI ();
}

    }

Here you create a Object (not object) and assign it to a GameObject, you can use a cast like @tomekkie2 said, or use GameObject.Instantiate.
Line64:

GameObject  newStructure = GameObject.Instantiate( allStructures[structureIndex], lastHitObj.transform.position, Quaternion.identity );

This is more of a C# design error, you can’t assign one part of a vector, you need to change the whole thing(its weird I know). you can do this by creating a new vector with the same values except the ones you changed then assign it.
Line66:

  newStructure.transform.localEulerAngles = new Vector3(
  newStructure.transform.localEulerAngles.x, 
  (Random.Range(0, 360)),
  newStructure.transform.localEulerAngles.z);

As for Line 95, you need to set the execution order for build panel tweener.
based on that error, is probably still in Unityscript(“Javascript”). are you planning to convert that to C#?
