Best way (talking about performance) to build a menu. OnGUI or 3D with ortographic camera.
Hey everyone. Just a performance doubt here. I heard a lot about the bad performance of the OnGUI class in Unity so I though about making my menu with planes filled with textures and use OnMouseUp.. etc, functions.
As my game is for mobile, I though it will also be better because I can't change the size of a font in OnGUI dinamically, but I can change the local scale of a 3D Text, what will make almost the same effect.
Just focusing on performance, which one is better?
Thanks from now!
So do not, under any circumstances, use OnGUI for mobile in game display - the performance is absolutely awful. I have specific advice from Unity that it should not be used due to the number of draw calls, the multiple calls per frame and the need to fully redraw the view if you use it. I am currently going through the process of a rewrite of the few bits of OnGUI I had and using NGUI instead and it has made a big difference.
However, if you are just drawing a menu that doesn't appear over live game play it will work. One of the big problems is the way that Unity optimises frame rate over UI events that means that if the rate drops (with the standard Xcode project for instance) then the buttons don't always work because input events are missed.
I have a couple of OnGUI elements appearing in the game. Like side tabs for weapon selection. I tried to optimize it as much as I can, so every element of this tab is just rendered either if the tab is opening or already opened. And.. we can surely see that the performance drop down a lot! I really hope they rewrite some of these things that are causing this awful performance, because OnGUI is a pretty powerful functionality if you take some time to figured out some tricks.
We can hope :) I understand that it has been in the works forever. I like OnGUI for editor stuff where it works well and I invested a lot of time in building a nice retained framework - all for nothing I think... Guess I should have done some performance tests first. NGUI is well worth a look if you ask me - it's doing what I need.
I really need to finish this project to be able to buy a GUI system, hahah! Fortunatelly, it's not a huge thing and I'm almost done, except for most of the GUI things. I'll build my menu with planes and 3D texts, this way I gain performance and the ability to increase text size to fit exactly the screen needs.
Does mobile support 3D Text? Because I set up a custom text, material with Text shader and everything but in the device I just see the squared shapes where the text should be! **Seems like the problem is with my custom font!
