Ok, I know that there are other Wrench Event guides, but they do not use correct grammar, so here is mine.
Multiple Rocket Launcher
1. Make 9 slanted print bricks.
2. Print them all to the letter O.
3. Hit every brick with the WRENCH and type 1 for the brick description
4. Do the same as 3 on all of the print bricks.
5. Make a trigger by making a small brick.
6. Hit the trigger with the wrench.
7. Go to events.
8. Click OnActivate, <NamedBrick>, 1, Spawn Projectile, and for this, rockets.
9. Type anything in the first three boxes.11.
The first three boxes are XYZ and XYZ are:
X: West or East (Ex. West, 5 0 0 § East, -5 0 0)
Y: North or South (Ex. North, 0 5 0 § South, 0 -5 0)
Z: Up and Down (Ex. Up, 0 0 5 § Down, 0 0 -5)
