This is my sentry and dispenser project continuation (not the last one)
2.0
- Now the buildings have a 3x3 area, and they have a mecanism 4 blocks deep, so it would be a problem in non flap maps, or inside places with more than one floor.
- The Sentry now have unlimited ammo and shoots in every direction.
- Both sentry and dispenser now only activates when theres someone in their range, your team for dispenser, enemy team for sentry, so now they dont just keep shooting.
- To summon tower, since sentry shoots every direction, eliminated the Z+ Z- X+ and X-, and now the Slot:0 is the sentry and Slot:1 the Dispenser.

2.1
-New mecanism using tellraw, now no matter which slot you use the "Construction PDA", will appear a message with
"- Sentry - - Dispenser -" options, that summon the buildings where you are.
