How do I find class CActor with cheat engine 6?

[Jackalhead]

What would I scan for to find Class CActor movement? I'm interested in adjusting the size scale and movement speed of my character. I found out how to change the barbarian's size. I continuously used his transformation skill and did scans for increased and decreased values. Once I found that, I was able to just adjust his size bonus modifier in the returned memory address.

However, I can't change my size as the other classes, nor can I adjust my speed. I understand that Class CActor movement contains both float ScaleSize at 0x01C and float Speed2 at 0x0B8 but how can I find these memory addresses with cheat engine?

Thanks in advance.
