After finishing the project, there are a few extra ways you can expand upon the script to add new elements. The repeat loop is the only statement in Lua that creates a block and that is not closed by the end keyword. It'll be useful while learning. The variable used in such loops is called the loop counter. All rights reserved. Lua is a multi-paradigm scripting language originally designed to be embedded as part of other, existing programs. It is then considered that the chunk is complete when nothing or the empty string is returned. The world is full of ifs and but a so why it wouldnt be present in the programming world. Since you've tested that finishRace() works, remove the test print statement to keep the script clean.

When naming a variable or a table field, you must choose a valid name for it. Is the God of a monotheism necessarily omnipotent? When the condition is false, they stop repeating the code and the program flow continues. This is mostly useful when compiling code to prevent people from getting the original source back. Lua, like most lanuages of this kind, has a "break" command that jumps out of the smallest enclosing loop. The following code sample shows how to break an infinite whiledo loop. -- Other code can be here and it will execute regardless of whether the code in the conditional statement executed. end You can use a whiledo loop to write infinite game loops by setting true as the condition.

If the first parameter given to the load function is a string, the chunk is that string. Thanks for contributing an answer to Stack Overflow! This is because one side is evaluated before the other side, so in left-to-right order it ends up going from x < y < z to true < z which is an error, whereas in the explicit method, it goes from x < y AND y < z to true AND y < z to true AND true, to true.
