How do I use the projectile taps in sou

[edit] How do I use the Projectile Taps in SoU

For this example, I'll make a Deadly Dart Trap.

On the Right Palett, select "Triggers", then "Traps > Deadly > Projectile Trap Trigger, Dart".
Draw the trigger where ever you want it. If you open the trigger propeties, you can make adjustments as you wish.
NOTE THE TRIGGER TAG! for this example, it should be "X0_TRAP_DART". Change it if you wish, but remember what the TAG is.
Now, you can use one of the Projectile trap object placeables if you whish, but this can really be any placeable you want to use, even an invisable object. Select a placable and place it where you want the projectile to come from.
Most important The TAG of the placeable must match the TAG of the Trigger. In this case, my placeable will also have the tag of "X0_TRAP_DART". The placeable should be marked static, but doesn't have to be. If you changed the TAG of the Trigger, be sure to use the same TAG here.

Thats all there is to it really.
