I was thinking this could be a mutliple addon thing.
Including Bricks, Tools, and Server scripts.
Tools would be
Geiger counter- Counts the amount of Alpha, Beta, and Gamma particles in the air near you. Uses a basic easy to read display at the bottom of your screen that says Alpha: 1-100%, Beta: 1-100%, Gamma: 1-100%. 1-15 would display as a blue text, 16-30 would display green, 31-45 would be yellow, 46-60 would be red, and 61-100 would be pink.
It would also show a display of already 15 gamma in light, and 1-15 beta and alpha anywhere else.
Explosions would give off +5 alpha, beta, and +6 gamma depending on the size, and fire would give off +2 alpha and beta, and +3 Gamma.
Bricks would be
Reactor Debris 1x1f, - Gives off 14+ Alpha and beta, and 24+ Gamma.
Reactor Debris 2x2f, - Gives off 17+ Alpha and beta, and 32+ Gamma.
Reactor Debris 1x1, - Gives off 21+ Alpha and Beta, and 43+ Gamma.
Reactor Debris 2x2, - Gives off 26+ Alpha and Beta, and 50+ Gamma.
Anti-Rad basic bricks - Blocks any and all Radiation
Anti-Rad Cubes - ^
Anti-Rad Zones - ^
Rad Zones - Gives off 5 alpha, beta, and gamma inside the zone only
Server scripts would be
RTB - Preffs
Disable/Enable
Minigame only
None Admin only
Kills at 110+
Blockables - Bricks
Beta emitters get blocked by any and all bricks/Static shapes (vehicles)/Moving vehicles ect.
Alpha emitters get blocked by any bricks, or Antibricks/zones, only
Gamma emitters get blocked by Antibricks/zones, Cubes, or Modter only, absorbed +6 by anything else.
Iv made my point for this, add as you wish.
