I decided from this section on to do the course in unity 5 and tackle some syntax changes and other minor diffculteis as they come, up untill now changes were easy to learn and implement in unity 5. the world canvas apperntly behavs totaly diffrent in unity 5 from waht is protraid by the lecture, and I just can’t recreate the work being done in the lecture, has anyone encoutred this? or know how to fix it? because if i can’t re-create it unity5 what’s the point in learning it?
I didn’t seem to have any problems converting them to Unity 5 after the lectures on the previous lessons. it ran fine and everything was good. When those lectures were created, only Unity 4 existed and the basic knowledge still applies. I remember @ben stating that in one of the earlier add-on videos. If there were major changes or updates they would make a new video and insert it into the lesson, but it was to cumbersome to redo the entire thing.
The next lesson “Bowlmaster” does use Unity 5 as it was out by the time they got to that one.
In my opinion, it’s a learning experience all the way around and if there’s something you can’t figure out, there is this awesome community and of course Google 
Could you be more specific about the behavior issues you’re having with the World Canvas? Maybe we could help. Several of us have completed the section using Unity 5.
In the videos he simply enters 1600 by 900 in the heigh of width scale of the canvas and it translates prefectly, same for the texture. in my tries it simply doesn’t. my texture had to be at the size of 32 * 18 when the canvas was 1920*1080 and I had to increase the camera size.
Inside of your splash scene check your canvas scaler is your UI scale mode set to scale with screen size? With that selected you should see reference resolution X textbox should be 1600 and Y textbox should be 900. I was able to develop the canvas as the video demonstrates.
