[HQ TUT] GUI Radar, rotating too! (Code breakdown & SRC) [/HQ TUT]

Step one: Imports.

First, we need to import the nessesary classes. This is only based on the assumption that you are using a seperate package for the class that I'm about to show you.



**
Step one: Complete.
**

Step two: Class declaration & Variables.

Ok. So, again, assuming you are coding this in another package, create these variables:



Forget the 'MediaClient.mc' etc. That's a base class I use. Find that one out yourself.

**
Step two: Complete.
**

Step three: The called method.

So now, we prepare the first method, and it's also the method we will be calling, from GuiIngame or your hooked class.



**
Step three: Complete.
**

Step four: The actual GUI radar method.
Now, we'll make the actual method that creates the instance of the entites, and displays them; aswell as using basic math to find the appropriate co-ordinates.





So now that's done, that's it. Feel free to customize the colours, or basically anything.

**
Step four: Complete.
**

Step five: Calling the GUI radar as a whole.



That's it!

**
Step five: Complete.
**

Finale.

Thanks all.
Figure out yourself what it looks like....
