Hey guys, I've created a quick event that shows how easy it is to use BlockLoop! As well as a companion video that you can view on youtube to follow along with while looking over the event instructions and comments I've written.

BlockLoop: https://ffhacktics.com/wiki/Event_Instruction_2A
BlockStart (Has valid block instruction list): https://ffhacktics.com/wiki/Event_Instruction_2F

The event itself is a little poorly planned lol, but hopefully you can see whats going on and get the idea! Please let me know if you have any questions, I'd be happy to explain any part of the event more.

Offset(x00002000)

SET(x007F,x0001)
//7F will control our loop that runs indefinitely until we tell it to stop (by setting it to 0000)
SET(x007E,x0005)
//7E will run 6 times since we set it to 5 and will set LoopAmount to 001 (# of loops = variable # + 1 with this setting)
SET(x007D,x0000)
//7D we don't care much about, BlockLoop is going to set it for us, same with 7C which I won't bother setting

{font:00}Hey FFHacktics!{br}
I'm here to show you how to use BlockLoop!{end}

//Message x02
{font:08}Jumza{br}
{font:00}BlockLoop is used to turn regular{br}
Blocks into loops.{br}
These loops will run{br}
independently from the rest{br}
BlockLoop requires Xifanie's{br}
Event Instruction Hack ASM.{end}

//Message x03
{font:08}Jumza{br}
{font:00}Rather than explaining all the details,{br}
I'm just going to run quick demo's{br}
for the 3 different "kinds"{br}
of loops you can create based on{br}
the first parameter, Loop Amount.{br}
All the nitty gritty is{br}
posted on the wiki under{br}
Event Instructions (2F),{br}
and you can see all the{br}
instructions laid out{br}
on the FFHacktics forum.{br}
video description!){end}

//Message x04
{font:08}Jumza{br}
{font:00}Important notes to remember!{end}

//Message x05
{font:00}1. You can't end an event while a{br}
block is running.{br}
2. You can have multiple BlockLoops{br}
in a single block.{br}
3. You can still only use instructions{br}
that can be used in regular Block's.{br}
4. Jumping by number of bytes rather{br}
than to last BlockStart is possible!{end}

Jumping back by # of bytes is not covered in this tutorial
