Unload & Preload Q's

#1 I just tried un-checking the preload and it did crash for me too.
So I guess you've found a bug. it used to work at some point. maybe 1.7.3?

#2 Now that I'm thinking about it. I never actually used it in the editor. but in my previous game, most of my images where not pre-loaded and it was all set through datablocks.cs . it saved me a couple of minutes of loading images when launching the game. it's a must have feature.

#3 It is especially a must have feature on the iPhone with its 24mb of share RAM. you can not load all your games data, not even when PVRTC is present (which will cut the texture sizes also in VRAM drastically to 4bpp / 2bpp from 32bpp)

#4 Thats the problem im having atm, ive stripped my game down to the point where I can fit everything in RAM at once. Obviously im pretty limited by it though.

#5 The check boxes in the editor don't always work. The only way to ensure it's working is to manually edit the datablocks.cs file.

#6 If you are having trouble with the level editor, I suggest that you open up the datablocks.cs file and manually changing the values as Conor suggested.

I personally have not had any of the issues mentioned here, and I will try to look into it.

#7 Check the box you want, then change one of the Drop downs and then switch it back. It doesn't know you've made changes unless you do that so doesn't save your check box changes. That's how I did it. Apparently checkbox changes don't set some global "change occurred in this window" variable so when you save nothing is actually saved.
