Using Loops to Change GUI Alpha

I am trying to change the alpha of a tool on a staff tool bar I made for a UC server, so I used a for loop to do so. Originally, doing this would work:

PHP Code:


		
			
DoctorStaffBar_Control0.alpha = 0.3;

DoctorStaffBar_Control1.alpha = 0.3;

DoctorStaffBar_Control2.alpha = 1;

DoctorStaffBar_Control3.alpha = 0.3;

etc.

Although my code got really long. So, I made a for loop and added a continue so that if the code got to the staff tool selected, the alpha would become 1. What's odd is that I echoed the code after I set the alpha, and it prints correctly. It doesn't show up on my GUI though. Yes, setting the text does work with this loop.

PHP Code:


		
			
function selectToolName(temp.staffCode) {

  temp.code = 0;

  for (temp.blah : getTools()) {

    if (temp.code == temp.staffCode) {

      temp.thing = "DoctorStaffBar_Control" @ temp.staffCode;

      DoctorStaffBar_Control_Text.text = getTools()[temp.staffCode][0];

      temp.thing.alpha = 1;

      temp.code++;

      continue;

    }

    temp.thing = "DoctorStaffBar_Control" @ temp.code;

    temp.thing.alpha = 0.3;

    temp.code++;

  }

}

Avoid using continue and break when you don't have to.

PHP Code:


		
			
function selectToolName(temp.staffCode) { 
  temp.code = 0;
  temp.tools = getTools();
  DoctorStaffBar_Control_Text.text = temp.tools[temp.staffCode][0];
  for (temp.code = 0; temp.code < temp.tools.size(); temp.code++) {
    temp.thing = ("DoctorStaffBar_Control" @ temp.code); 
    if (temp.code == temp.staffCode) { 
      temp.thing.alpha = 1; 
    } else {
      temp.thing.alpha = 0.3;
    }
  } 
}

Hey,

Thanks for your quick reply! Unfortunately, this does not change the alpha of the image like I stated. I'll give you my full code if that helps.

PHP Code:


		
			
//Scripted by Graal801624

function onActionServerSide(cmd, temp.staffCode) {
  //What happens if the player activates one of the tools.
  if(cmd == "staffbar") {
    switch(temp.staffCode) {
      case 0:
        //Boots
        echo("The player activated Tool One");
      break;
      
      case 1:
        //Drag
        echo("The player activated Tool Two");
      break;
      
      case 2:
        //Staff tag
        echo("The player activated Tool Three");
      break;
      
      case 3:
        //Testing
        echo("The player activated Tool Four");
      break;
    }
  }
}

//#CLIENTSIDE
function getTools() {
  //In the return, type the tools with an image.
  return {{"Tool 1","red.png"},{"Tool 2","orange.png"},{"Tool 3","yellow.png"},{"Tool 4","green.png"},{"Tool 5","blue.png"},{"Tool 6","purple.png"}};
}

function getDefAlpha() {
  //Type here what you want the default non-selected alpha to be.
  return 0.3;
}

    selectToolName(this.staffCode);
  }
  
  if(keyname == 56) {
    //Number 8
    this.staffCode = 7;
    selectToolName(this.staffCode);
  }
  
  if(keyname == 87) {
    //Activate selected staff tool with w
    triggerServer("gui", this.name, "staffbar", this.staffCode);
  }
}

function selectToolName(temp.staffCode) { 
  temp.code = 0;
  temp.tools = getTools();
  DoctorStaffBar_Control_Text.text = temp.tools[temp.staffCode][0];
  for (temp.code = 0; temp.code < temp.tools.size(); temp.code++) {
    temp.thing = ("DoctorStaffBar_Control" @ temp.code); 
    if (temp.code == temp.staffCode) { 
      temp.thing.alpha = 1; 
    } else {
      temp.thing.alpha = getDefAlpha();
    }
  } 
}

Thanks,

Change:

temp.thing = ("DoctorStaffBar_Control" @ temp.code);

To:

temp.thing = makevar("DoctorStaffBar_Control" @ temp.code);

KeyPress can be shortened, unless you plan to changing it from the number keys:

PHP Code:


		
			
function onKeyPressed(keycode, keyname) {
  temp.code = keycode - 49;
  if (temp.code < getTools().size()) {
    selectToolName(temp.code);
  }
  else if (keycode == 87) {
    //Activate selected staff tool with w
    triggerServer("gui", this.name, "staffbar", this.staffCode);
  }
}

Hey,

Thanks for your help! I was wondering if there was a function to make a variable, thanks for pointing it out. Cheers! I'll post the whole script in the code gallery when I'm done :)

Yes, I had actually planned to change it in the future, but thanks for the snippet :)
