I have two scripts here, one for my main menu and one for my game UI
the problem is when i attach these scripts they wont show up nicely in android output (they are really small) i dont have this problem while playing the game in unity.
i can not use the canvas scale because i am not using the unity's UI system. these scripts are from the air strike starter pack.
can anyone help please?

 

Is there a specific reason that you use the old OnGUI / (IMGUI) and not the (new since 4.6) uGUI?
Its better performing, better to handle and can be easy scaled to all resolutions.

For a quick start into the uGUI check out the official video tutorials:
https://unity3d.com/learn/tutorials/topics/user-interface-ui

 

Thanks for your reply
I am using this package called "air strike starter pack" and these scripts are included in that package.
I am making this game for a school project so i started modifying this package's demo scenes and I dont have enough time to get into details on making the game's UI with the unity's new UI system.
i am just looking for a quick solution.

 

if that's a paid asset you really shouldn't be redistributing the source code openly... something to be aware of.

 

To tell you the truth there is no easy solution to the problem.
The rect 's that define how big your ui elements are, are defining the size at a fixed pixel size so it does not scale at all for your screen size on your mobile device.
You would have to redefine every size in the ui to be a percentage of the screen width / height.
