GD.tag button

[Bow Man]

Hi, I trying to make a button when pressed, will display a JPEG image. However I have no clue as to how the GD.tag and the GD.get_inputs work, tried referring to the blob and selftest example scripts but don't understand...

Here is how I do this:
Before you draw the button, you set the TAG which should be related to your button.

//My next button being drawn should become TAG 1
GD.TagMask(1);
//Now draw a simple button with a star on it:
GD.cmd_button(0,0,50,50,18,0,"*");
//Do not forget to switch TagMask to avoid further drawing commands also being tagged "1"
GD.TagMask(0); //Can be omitted if there are no further drawing command befor GD.swap();


At some Point in your code you now request the inputs, I do that normaly directly after GD.swap();
GD.get_inputs();

Now, GD.inputs.tag has the value of any tag being touched - if there was any touch.

if (GD.inputs.tag==1) {
//My button with tag 1 was pressed
...
}

See page 22ff in the manuel from 2.6 "Touch tags" to 2.7 "Game: Simon"
That also explains what you need.
