Problem using if

maty64

when i use if its says that it needs a Expected conditional expression after "if".

and I dont know what to put in there

maty64 the "if" needs to make something happen. So you're likely missing a line of code somewhere. If you don't, your program doesn't know what to do after that condition (IF) occurs. Basically:

if _myVariable == 0:
    ### this is where what needs to happen happens

Post the code and the exact error message.

If you have never programmed before I recommend reading through a Godot or Python introduction. This is not something you can guess your way through, and tutorials in my opinion will leave gaps. Better to take an intro class.

I believe this is a pretty good explanation: https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_basics.html#if-else-elif

This; "Expected conditional expression after "if"." keeps appearing

G_Godot147741 you need something after the if. A comment isn't enough. If you don't want to do anything, put "pass".

Like this:

if _myVariable==0: pass

You can learn more about "if" there: https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_basics.html#if-else-elif

This behavior (needing something to do, a comment not being enough) is a design shared by Python. You can find a good discussion there:
