endYes. Lua doesn't have multidimensional arrays, just arrays of arrays, i.e.intensity wrote:blocks[1][1] would screw up if blocks[1] had no value?
Code: Select all
blocks = {} -- blocks can be used as an array but blocks[1] has no value
blocks[1][1] = 1 -- errors, blocks[1] is nil
blocks[1] = {} -- now blocks[1] can also be used as an array
blocks[1][1] = 1 -- worksNot a compiler. Interpreter.intensity wrote:What's wrong with this line? The compiler says "attempt to index field '?' (a nil value)".

Actually Lua is both, the compiler translates source code into bytecode and the VM interprets the bytecode to carry on the operations defined in the source code.zac352 wrote:Not a compiler. Interpreter.
That's an interpreter. Note: I know that lua has a compilable file for making a lua compiler. so yeah.leiradel wrote:Actually Lua is both, the compiler translates source code into bytecode and the VM interprets the bytecode to carry on the operations defined in the source code.zac352 wrote:Not a compiler.

Yeah, that's debatable. I was just pointing that Lua actually compiles things.zac352 wrote:That's an interpreter.
