Variable Manipulation - Tbot1000 - Aug-31-2020
I have been working on a game which involves leveling up skills through different tasks. When a person types /m in the console and is in the coal mine, among other things the mining_skill variable is supposed to increase. No errors are returned, however, the variable does not increase, it will alternate from 5 to 3. In the program, you can see the variables by typing /skill
I tried condensing the program and setting it up the same way and that works perfectly fine - for some reason this doesn't. Thanks!

RE: Variable Manipulation - Tbot1000 - Aug-31-2020
There doesn't seem to be any problem with
mining_skill = mining_skill =+ 5...
I must be missing something obvious here.
RE: Variable Manipulation - buran - Aug-31-2020
it should be either
mining_skill = mining_skill + 5or
mining_skill += 5at the moment you are just comparing
mining_skill and the result of evaluation of mining_skill =+ 5. My initial thought was it should throw an error, but obliviously it's a valid code - chained assignment>>> spam = eggs = 'foo' >>> spam 'foo' >>> eggs 'foo'in your case
spam and eggs are both maining_skills
RE: Variable Manipulation - bowlofred - Aug-31-2020
x += 3is a shorthand to increase a number by a value. You have instead:
x = x = +5Theres no incrementing, just setting a variable (twice, sorta)
RE: Variable Manipulation - Tbot1000 - Aug-31-2020
Ah. I believe this is the proper syntax for C++, I think I just confused them. Thanks a bunch!

x = +5
x = x
It is the same in C++ and Python. Will not throw an error, but not correct code unless you just want to set x to the value 5.
You may have been thinking of x = x += 5. As with the earlier example in C++ this is syntactically valid and nonsensical. It evaluates as
x += 5
x = x
And x += 5 evaluates as x = x + 5
This code adds 5 to x, but the extra assignment is unnecessary.
In Python x = x += 5 is invalid code.
