Map Requirements
Bomb Sites
Create a brush textured with tools/toolstrigger, and with it selected, press Ctrl+T and change the entity class to func_bomb_target.
Main article: func_bomb_target
If such an entity exists, the game will care about the rest, such as appropriate round endings and giving one Terrorist a C4 at round start.
Though the official Bomb Defusal maps have two bomb sites, the Bomb Defusal Scenario will work correctly with just one. If a map has no func_bomb_target, no bomb planting will be possible.
Competitive Aspects
- Bomb sites are located closer to the Counter-terrorist's spawn area so that they can get into a defensive position before Terrorists arrive.
- Each bomb site should require two entrances; Mostly, a cover is set up at a bomb site so that a player can watch one entrance while being covered from the other.
- Think about safe planting spots and whether they should (or not) be there (for a specific direction).
- Remember to eliminate bomb-stuck spots all across the map using trigger_bomb_reset entities and wise clipping.
- Prevent bomb defusal through walls using func_no_defuse entities.
Tip: Place letter overlays or decals around the bomb site so players can find and identify each site.Tip: Visualize where players can plant the bomb, i.e. the bounds of the func_bomb_targets.
