Static variable and Materials

Questions & Answers
1

Hi there! im trying to create smt like lego game. Now im trying to create system, thats allow player to choose between several (actually 66) materials for blocks. here is the code: (java)

var boxIconTextures : Texture[];
var materialsRepresentation : Material[];

static var MaterialOfElement: Material;

function MaterialOfElementChange() {

var materialSelectionGridInt : int = 0;

materialSelectionGridInt = GUI.SelectionGrid (Rect (25, 80, 700, 480), materialSelectionGridInt, boxIconTextures, 16);
    switch (materialSelectionGridInt) {
        case (materialSelectionGridInt): materialsRepresentation[materialSelectionGridInt] = MaterialOfElement; print ("material switched"); break;
    }
}

and here is code for element creating:

var BoxTexture;
var check ;
var thePosition ;
var Brick : LayerMask;
static var MaterialOfElement;

function Fire () {

thePosition = transform.TransformPoint(Vector3.forward * 1.5);

check = Physics.CheckSphere (thePosition, 0.3, Brick);

if (check == true)
return;
if (check == false)

var element = GameObject.CreatePrimitive(PrimitiveType.Cube);
element.renderer.material.mainTexture = BoxTexture;
element.layer = 8;
element.renderer.material = CubeGui.MaterialOfElement;
element.gameObject.AddComponent ("Destroy");
element.transform.position = thePosition;
element.gameObject.AddComponent ("SetToGrid");
}

the problem is: im choosing new material from MaterialOfElementChange() but its wont apply on creating objects. i manage that its happen cos of mistakes in MaterialOfElementChange() but everything looks like its work correctly. may be its happen cos static vars not allow to use it for materials? :D (cant believe that)

edit1: ive tryed what Simple says, but it wont work. i find out that when i start script of material change (ongui part) its says "material changed" lol so i gonna check some docs on grids and toolbars.

edit2: forget to say:

materialsRepresentation = new int[10];

equals

Cannot convert 'int[]' to 'UnityEngine.Material[]'.

array is created via inspector, so, somehow grid just dont want to work. maybe its happen cos of another toolbar in same script?

switch (materialSelectionGridInt) { case (materialSelectionGridInt): materialsRepresentation[materialSelectionGridInt] = MaterialOfElement; print ("material switched"); break;

I suppose your switch-case doesnt work. It should be like:

switch (materialSelectionGridInt) {
//if (materialSelectionGridInt==1)
        case 1: materialsRepresentation[1] = Material1; 
print ("material switched"); break;
//if (materialSelectionGridInt==2)
        case 2: materialsRepresentation[2] = Material2; 
print ("material switched"); break;
//etc
//...
}

UPDATE: And I am not sure byt you have created empty and not editable array "materialsRepresentation" because you use BuiltIn array. And you need to add this

materialsRepresentation = new int[10];

Because you cant resize BuiltIn arrays without reinitializing. http://unity3d.com/support/documentation/ScriptReference/Array.html

Problem was here:

materialsRepresentation[materialSelectionGridInt] = MaterialOfElement;

must be:

MaterialOfElement = materialsRepresentation[materialSelectionGridInt];
