New to hacking.
Is there a feature in CE to actively scan if an address's opcode is changed?

Are you trying to reverse a trainer?

Well uh, you can scan for changed/unchanged values as you toggle stuff?

That was a pretty sharp guess apparently.

Memory integrity checkers do that.
Locate your opcodes, there are just memory bytes in the end.
Write a code that adds up all the bytes of the opcode which you wish to study and stores the result somehwere. Perform this action repeatidly and compare the new result to the previous result everytime.
If the new result differs from the previous one, the opcodes have been changed.
Potentially after your perform the results comparison you make a conditionnal jump, if the resutls are equal nothing special happens but if they differ you make the code take a road which includes a breakpoint, then you go and find what exactly happened to your opcode.
