==No Grenade Areas - "nogrens"==

A "nogrens" area is defined as an area where grenades will not explode - hence "nogrens". To create a "nogrens" area in your map all you need to do is create a brush, click "tie to entity", choose trigger_ff_script, and then name it "nogrens". Then, in your map's .LUA file be sure to include base_teamplay.lua as such:

<pre>-- Map's LUA file

-- Include nogrens functionality
IncludeScript( "base_teamplay" )</pre>

===How It Works===
The way a "nogrens" area works is that before the grenade goes to explode it checks to see just exactly what entities it is touching. It then asks those entity if it can explode. If any of the entities respond back with "false" then the grenade can not explode. The LUA function that answers the question if the grenade can explode is "canexplode" (as seen in the example) so if you want to override default "nogrens" behavior then your custom "nogrens" lua object will need to have a "canexplode" function.

===Example===
If you wanted red team to be able to throw grenades in an area (and have them explode) but blue team not be allowed to do that then you can do that. There are really only two changes you would need to make. First, name your "nogrens" area (in hammer) to something else - like "blue_nogrens". Then, modify your map's lua file thusly:

<pre>-- Map's LUA file

-- Define "blue_nogrens"
blue_nogrens = trigger_ff_script({})

-- Let red team's grenades explode but not blue team's
-- here we define the "canexplode" function
function blue_nogrens:canexplode( ent_id )
if IsGrenade( ent_id ) then
-- Allow red team
if ( GetObjectsTeam( ent_id ) == RED_TEAM ) then
return true
else -- Disallow everyone other team
return false
end
end

-- Return normally for anything not a grenade
return true
end</pre>
