Unary Operators

[sudo_radish]

Is there a list of Unary operators that is used in Love?

You are looking for Lua's unary operators, not LÖVEs, since LÖVE isn't a language.

The lua reference lists the minus, length operator (#) and "not":

Thanks for the feedback.

I did check the Lua docs first but I didn't know if Love had some modified stuff in it like Pico 8 does.

it is mainly because I am a touch lazy and I like the way I can do

Code: Select all

a+=1

or

Code: Select all

a-=1

over

Code: Select all

a = a+1

.

Stupidly I tried it first and got a great big fat error on compile lol. And I didn't want to think I missed something obvious.

+= and -= aren't unary operators though, they are a special case of assignment operators (and Lua as used in Löve only has the assignment operator '=' (singular).

Assignment operators look like infix operators but they actually aren't since

a) they don't form an expression / yield a value (can't do print(a = 3) is illegal)
b) the left hand side can't be any expression, it must be a variable (can't do 3 = 3)
