Loops

There are while and for loops in HLF.

While loops

You can write while loops like this:

while(condition){
    // code here is ran as long as the condition evaluates to true
}

For loops

You can write for-loops like this:

for(<initializer>;<condition>;<increment>) {
    // loops content goes here
}

When the loop is run, the initializer is run first, it is typically used to initialize a counter variable. After that the loops begins and runs like this:

• Condition is evaluated, loops stops if the condition is false
• Loops content is run
• Increment statement is run

An example of a classic usage of a for loop is:

for(int i = 0; i < 5; i++) {
    say(i);
}

This code would print all numbers from 0 to 4 to the chat

Limitations

Loops are limited by the maxCommandChainLength-gamerule. By default, it is set to 10000000 when a datapack loads. This is to prevent unintuitive behaviour. This (hopefully) is a temporary solution.
