Hey guys, would someone please show me how to add GUI, and have it execute code when tapped?
also, why wont this work?

function useItem(x,y,z,itemId,blockId,side)
{
if (itemId==280)
{
	 function bl_removeEntity(ent)
	 {
	 bl_removeEntity(64);
	 }
}
	
}
function attackHook(attacker, victim)
{
//Your Code Here
}
function modTick()
{
//Your Code Here
}

it's supposed to remove all dropped items when the stick is tapped ( i want it so when a GUI button is pressed it removes them).

Please help.

Thanks!

Here you are:

var ctx = com.mojang.minecraftpe.MainActivity.currentMainActivity.get(); //A variable for the MCPE activity session
var GUI = null; //A variable for the button
function  newLevel() { //When you start a world
  ctx.runOnUiThread(new java.lang.Runnable({ run: function() {
        try {
          GUI = new android.widget.PopupWindow(); //The button becomes real as an android window
          var layout = new android.widget.RelativeLayout(ctx); //Variable for the layout (can be Linear instead of relative)
          var button = new android.widget.Button(ctx); //A variable for the ACTUAL button we see
          button.setText("Remove"); //The text which will be on the button
          button.setOnClickListener(new android.view.View.OnClickListener({
                onClick: function(viewarg) { //Perform a function when the button is pressed
                  //Insert the code of what will happen when the button is pressed
                }
          }));
          layout.addView(button); //Adds a button the our chosen layout
          GUI.setContentView(layout);
          GUI.setWidth(android.widget.RelativeLayout.LayoutParams.WRAP_CONTENT); //Width of the button. We didn't specify the amount of pixels, so don't worry.
          GUI.setHeight(android.widget.RelativeLayout.LayoutParams.WRAP_CONTENT); //Height of the button. We didn't specify the amount of pixels, so don't worry.
          GUI.setBackgroundDrawable(new
android.graphics.drawable.ColorDrawable(android.graphics.Color.TRANSPARENT)); //Specifies whether the button is transparent or not.
          GUI.showAtLocation(ctx.getWindow().getDecorView(), android.view.Gravity.RIGHT | android.view.Gravity.BOTTOM, 0, 0); //Specify where the button will be on the screen. In this case it will be in the bottom right corner
        }catch(problem){
          print("The button can't be shown because " + problem); //Tells us the problem if the button cannot be displayed
        }
  }}));
}

function leaveGame() { //If we are exiting a world
  var ctx = com.mojang.minecraftpe.MainActivity.currentMainActivity.get(); //The variable for the MCPE session
  ctx.runOnUiThread(new java.lang.Runnable({ run: function() {
        if(GUI != null) { //If the button is on the screen
          GUI.dismiss(); //Dismiss the button
          GUI = null; //Reset the button
        }
  }}));
}
//Your code

You should never have a function that you will not use so in this case remove function attackHook and function modTick

The button can't be shown because Button window is not defined.

i tried it. it doesnt work... The button can't be shown because Button window is not defined.

what to do?

Sorry about that, I just accidentally used an undefined variable. I just updated my post with the GUI script. If you want to know how to remove all dropped item entities, I suggest you ask 500ISE on the BlockLauncher thread. It might not even be possible....

You can remove them. MrARM did in his too many items mod. I need it for my NukePE mod to kill lag.

I tried it, but there is no GUI. no error, but no GUI.

Because the button isn't doing anything...

how do i change its position?

In the line

GUI.showAtLocation(ctx.getWindow().getDecorView(), android.view.Gravity.RIGHT | android.view.Gravity.BOTTOM, 0, 0);

You can change RIGHT to LEFT and you can change BOTTOM to TOP. At the end, the first number (0) indicates how many pixels you want the button to be moved vertically and in the opposite direction. The second number (0) indicates how many pixels you want the button to be moves horizontally in the opposite direction. E.g. If the position is RIGHT,BOTTOM and the numbers are (100,120), the button would be 100 pixels away from the right side and 120 pixels away from the bottom.
