Swapping multipul textures on mouse over using raycast

Questions & Answers
1

hi Im trying to swap a texture that is always present in the middle of the screen. so that if it is over nothing it always shows the tooth, if it is over a person collider tagged “switch” the speech texture comes up and the tooth texture disappears, this i achieved.

Then i added another texture “pals” to swap when it was over a collider with the tag “pals” then the pals texture swapped ok, but the switch texture stopped working as soon as I added

else if(hit.collider.gameObject.tag == "pals"){ currentChar1 = hit.collider.gameObject; leaf1 = true; }.

can anyone tell me where i have gone wrong please.

private var currentChar1 : GameObject;
private var currentChar2 : GameObject;

var mouser : boolean;
var leaf1 : boolean;

var tooth : GUITexture;
var speech : GUITexture;
var leaf : GUITexture;

function Update() {
var hit : RaycastHit;
	if (Physics.Raycast(transform.position, transform.forward, hit , 15)){

	
	if(hit.collider.gameObject.tag == "switch"){
		currentChar2 = hit.collider.gameObject;
		mouser = true;

	}
	
	else if(hit.collider.gameObject.tag == "pals"){
		currentChar1 = hit.collider.gameObject;
		leaf1 = true;
	}
	
	else {
		mouser = false;
		leaf1 = false;
		}
	}

	textureSwapper();
}


function textureSwapper(){
	if (mouser == true){
		tooth.enabled=false;
		speech.enabled=true;
	}

	if (leaf1 == true){
		tooth.enabled=false;
		leaf.enabled=true;
	}

	else {
		tooth.enabled=true;
		speech.enabled=false;
		leaf.enabled=false;
	}

}

I would guess you need to set mouse = false in that new clause.

I went through and made sure that they variables and ifs were balanced with true and false.
I am having the same issue.
The speech texture used to swap with the tooth texture until I added the leaf texture “else if” statement

Now the leaf texture is swapping with the tooth texture
But the speech texture isn’t swapping with the tooth texture

I hope that makes sense.

I have also seen that the variable is switching on and off as it should just the texture isn’t showing.
I have also paused the player and switched on and off the texture to make sure it is visible at the correct coordinates and it is showing ok.

var mouser : boolean;
var leaf1 : boolean;

var tooth : GUITexture;
var speech : GUITexture;
var leaf : GUITexture;

function Update() {
var hit : RaycastHit;
	if (Physics.Raycast(transform.position, transform.forward, hit , 15)){

	
	if(hit.collider.gameObject.tag == "switch"){
		currentChar2 = hit.collider.gameObject;
		mouser = true;
		leaf1 = false;

	}
	
	else if(hit.collider.gameObject.tag == "pals"){
		currentChar1 = hit.collider.gameObject;
		leaf1 = true;
		mouser = false;
	}
	
	else {
		mouser = false;
		leaf1 = false;
		}
	}

	textureSwapper();
}


function textureSwapper(){
	if (mouser == true){
		tooth.enabled=false;
		speech.enabled=true;
		leaf.enabled=false;
	}

	if (leaf1 == true){
		tooth.enabled=false;
		speech.enabled=false;
		leaf.enabled=true;
	}

	else {
		tooth.enabled=true;
		speech.enabled=false;
		leaf.enabled=false;
	}

}

Two weeks later and I still havent figured this out.Is there anyone out there at all that could help its doing my head in…

ok I figured it out :slight_smile:

private var currentChar1 : GameObject;
private var currentChar2 : GameObject;

var mouser : boolean;
var leaf1 : boolean;
var tooth1 : boolean;

var tooth : GUITexture;
var speech : GUITexture;
var leaf : GUITexture;

function Update() {
var hit : RaycastHit;
	if (Physics.Raycast(transform.position, transform.forward, hit , 30)){

	
	if(hit.collider.gameObject.tag == "switch"){
		currentChar = hit.collider.gameObject;
		mouser = true;
		leaf1 = false;
		tooth1 = false;
	}
	
	else if(hit.collider.gameObject.tag == "pals"){
		currentChar = hit.collider.gameObject;
		leaf1 = true;
		mouser = false;
		tooth1 = false;
	}
	
	else {
		mouser = false;
		leaf1 = false;
		tooth1 = true;
		}
	}

	textureSwapper();
}


function textureSwapper(){
	if (mouser == true){
		tooth.enabled=false;
		speech.enabled=true;
		leaf.enabled=false;
	}

	if (leaf1 == true){
		tooth.enabled=false;
		speech.enabled=false;
		leaf.enabled=true;
	}
	if (tooth1 == true) {
		tooth.enabled=true;
		speech.enabled=false;
		leaf.enabled=false;
	
	}

}
