Important changes to find when importing a Construct 2 project to Construct 3

I've been using Construct 2 for years and just purchased Construct 3. I'm happy with it already but have a fairly large project I just imported into Construct 3. Everything seemed to work great for the most part, as I played for a while to see if any huge issues, but now I'm finding a few things that needed to be updated everywhere.

What I have found so far:

• Construct 2 distance(x1, y1, x2, y2) -> Construct 3 distance(x1, x2, y1, y2)
• Angle is ditto above (and probably all similar expressions
• Effects with colors are consolidated from 3 expressions of R, G, B to one expression using RGB255() system expression (or a few others you can use)

Posting this to help others but would also love if any other differences were pointed out so I can make the change and not have to find them the hard way!

Also, feel free to link to other forum or blog posts. I did a quick search but not a lengthy one.

...okay, now I went back to Construct 3 and the distance and angle has not changed. Either I was looking at something else or am going crazy . . .

Yeah, I'll probably delete the post or at least edit the original post so I don't mislead people . . . but I swear I triple checked the distance and angle expression, each, and it was different. Then after writing the post I went back and it wasn't. So either I am going crazy right now or I was pulling up a different expression?

But it would be helpful to know if anything else changed . . . or to know what I was looking at . . .

Everything you need to be aware of is documented in the manual under Importing C2 projects and The C3 runtime.
