Trackables

[Rabarber]

I've heard of Trackables, and i realized that they are spots on the screen that are clickable. But i have some questions about them.

1 - Do trackables cover a area of the screen or are they always the same size?

1b - If you are able to set their area - how small is it able to be?

2 - What would be the JASS code to create a trackable in the upper right corner of the screen?

3 - How do i create an event for a Trackable being clicked?

4 - Are there any downsides using Trackables? Except being unable to be removed?

Thank you.

A trackabe is a object with a model, so it's the size of the model that determines the size which can be clicked.
If you for example set the model to "units\\human\\Footman\\Footman" then you will have a trackabe with the size (and look) of an ordinary footman.
So, the smallest size possible is as small as the smallest model you can find.

Downsides: Probebly as slow as the 'unit is selected' event. Recuires extra work to get a 'Clicking Player' fake event response. AFAIK compleaty untested in a real multiplayer map.
