info_map_parameters is a point entity available in Left 4 Dead series.

Important:This is a preserved entity in .
If the game has round restart mechanics this entity may not behave as expected:

• On a new round entities with this classname will intentionally not reset. You can use logic_auto to emulate resetting it.
• Killing it removes it forever, as it is not respawned on a new round.
• It cannot be spawned with a point_template.
• Parenting this with non-preserved entities may have undesirable effects.

This entity determines the density of all item spawns and weapons spawned with weapon_spawn. It does not work on specific weapon spawnpoints such as weapon_rifle_spawn. If you want to control spawnpoints for specific guns, use weapon_spawn and force it to only spawn a specific gun.

The item density is calculated per 100 square yards. Which is the eqivalent of a hammer cube with each side being 360 units long.
1 inch = 1 unit. 1 yard = 36 inches/units. 100 square yards = 10x10 yards (360x360 inches/units).

Todo: This need to be validated. The numbers were taken from different cases where hammer units were equated to real life measurements.

Keyvalues

Inputs

UpdateCvars

Stuff values from this entity into cvars for tweaking

Important:Use this input only for tweaking and not while running the map. It sets the director_scavenge_item_override cvar to 1 and it's not reset to default value in next map. Which means map that uses this may break item spawning in next chapter or even in different campaigns.

ConCommands

Cvar/Command	Parameters or default value	Descriptor	Effect
director_solve_item_density	<int>		Pass the number of items you'd want in this map and this spits out the map density value.
