I recently upgraded from unity 4 to 5.4 and to my surprise the game is running more smoothly specially around trees.
Why I only now upgraded to unity 5 was because I did not believe it would boost the game in anyway specially in how unity handles custom mesh data (I wish unity would take arrays as references or at least give an option so that I can give it an array with an integer to let it know of how much of the array I'm using so I don't have resize the array every time...).
I also began to reprogram the GUI for the game, because it was lacking in features and it was quite a pain to work with, why I don't use an existing GUI is because I know what I want from it and I can optimize it for that purpose and to make it work the way I want it to. You might think it's reinventing the wheel and you would be right but if people don't at least study or try to create something that has already been done they don't advance as a programmer, besides I've already done this once and I can create modding support and modding tools for it at the same time.
I've also been thinking if I should sell the GUI in the Asset Store, but I'm not sure if anybody will buy it and if it's worth all the hassle to get it into the Asset Store. I also been thinking if I should join Patreon and if I do then I'll just share it for free there...
More on the GUI, it will be fast, responsive, automatic scaling and relocation based on resolution, it will have buttons (with a delegate, mouse over, down and normal textures and a tooltip), uniform and sliced scaling, text (which is rendered from a bitmap), able to use a texture and render it in a circle with a varying central angle and to create a drop down menu with menu items hidden outside the menu even when scrolling, the GUI will be stored in an XML file and if the GUI was not saved it will be also serialized to the scene or prefab so no changes will be lost, also because it can be saved into an XML file changing the GUI while the game is running is possible and it's possible for the user to change the GUI, this of course can also be disabled, the GUI can be modified either via the scene or script.
