Gmod Lua Error List

Jump to: navigation, search

Fix difficulty: Easy
Description: You tried to call a function that doesn't exist.
Possible causes:

• Your function might be defined in another lua state. (IE. Calling a serverside function on the client.)
• You're using a function on the wrong kind of object. (IE. Trying to call SetTarget() on a player.)
• The function you're calling has an error in it which means it is not defined.
• You've simply mispelt the name of the function.
  Ways to fix: Check your function calls for spelling errors. E.g. Entity.Kil will throw this error, use Entity.Kill and it'll be fixed right away!

Fix difficulty: Medium
Description: You tried to perform arithmetic (+, -, *, /) on a variable that's nil. (isn't defined yet)
Ways to fix: Make sure before you use variables you check if they're nil. Using variables which equal nil can lead to lots of errors.

Fix difficulty: Easy
Description: You tried to assign an index on an array that's nil. (isn't defined yet)
Possible causes:

• The array might be defined somewhere else, or in another lua state.
• Spelling errors.
  Ways to fix: Make sure before you use arrays you check if they're nil.

Fix difficulty: Easy
Description: You messed up a number, somehow.
Possible causes:

• Smashing on the keyboard while having a lua file opened in some text editor.
  Ways to fix: Remove the malformed number.

Fix difficulty: Easy
Description: You typed a symbol in the code that Lua didn't know how to interpret.
Possible causes:

• You didn't respect the syntax of a structure (IE. you forgot a 'then' after an 'if').
• You used an uneven number of brackets or closed them at the wrong places.
• You're using the wrong kind of operator (IE. '=' instead of '==').
  Ways to fix: Be on the look out for any characters you typed in by accident.
