How to make on/off-like gui-button?
Hello everyone, basically I need a gui-button that turns lights ON when pressed first time and OFF when pressed second time and so on, like a lightswitch.
Here is the code that I've managed to create so far:
using UnityEngine;
using System.Collections;
public class LightCtrl : MonoBehaviour {
//This Script controls cars lights
public Light Lowbl; //Assign a Lowbeam-left light
public Light Lowbr; // Assign a Lowbeam-right light
private float diff = 1;
void FixedUpdate(){
diff = (Screen.width / 16.8f) / 100;
}
void OnGUI() {
if (GUI.Button (new Rect (1110 * diff, 640 * diff, 60 * diff, 60 * diff), "LOW")) {
BtnLow();
}
}
private bool isClicked = false;
void BtnLow(){
if(isClicked){
isClicked = LowOn();
}
else{
isClicked = LowOff();
}
}
void LowOn(){
Lowbl.intensity = 3.0f;
Lowbr.intensity = 3.0f;
}
void LowOff(){
Lowbl.intensity = 0.0f;
Lowbr.intensity = 0.0f;
}
}
And I get error "Cannot implicitly convert type void' to bool'" and per usual I'm not very fond with coding so I appreciate if you can answer with example code/script with explaining. I hope that you understand me and thanks for everyone who helps in advance.
I, you just forget to return somthing in your functions ^^
void BtnLow(){
if(!isClicked){ // Here test if light are NOT (the "!") been clicked
isClicked = LowOn(); // Here you ask for a boolean return
}
else{
isClicked = LowOff();
}
}
bool LowOn(){ // so here you must say that this function return a boolean (void mean that the function return nothing)
Lowbl.intensity = 3.0f;
Lowbr.intensity = 3.0f;
return true; // return true when it's on
}
bool LowOff(){
Lowbl.intensity = 0.0f;
Lowbr.intensity = 0.0f;
return false; // return false when it's off
}
Hi, thank you @Veldars for quick response. I changed both void to bool and put return, but somehow it just doesn't work I only get either ON function or OFF function but not both.
Arf my mistake I forget to change my boolean (I edit my answer)
Hi,thanks @Wonde please use mention code by Veldars,its working fine.
Well thank you @Veldars it is working now, I appreciate this a lot.
I answered you one hour ago... But still waiting for moderation...
Hello,
void type can not convert in bool,it can be use only for condition true or false,
your modified code is given below.
if(isClicked) { LowOn(); }
else { LowOff(); }
Hi @ramp, I also tried this and it gave me same thing as below, it only gives me ON function or OFF function depending if " private bool isClicked = " is true or false.
Hi,
What you need is a Toggle, which is a Button that has two state.
Actually, i'm doing everything from script so this is what it looks like for your example :
public Toggle toggle; /* Assign from the editor */
void Start() {
toggle.onValueChanged.AddListener(ChangeLow);
}
public void ChangeLow(bool state)
{
if(state)
{
LowOn();
}else{
LowOff();
}
}
void LowOn(){
Lowbl.intensity = 3.0f;
Lowbr.intensity = 3.0f;
}
void LowOff(){
Lowbl.intensity = 0.0f;
Lowbr.intensity = 0.0f;
}
