ms_npc

Identical Entities

  • msmonster_skeleton
  • msmonster_troll
  • msmonster_giantrat
  • msmonster_giantbat
  • msmonster_orcwarrior
  • msmonster_orcberserker
  • msmonster_orcarcher
  • msmonster_orcranger

Any pointentity prefixed with msmonster_ will functionally be identical to ms_npc. Feel free to use the different named entities organizationally, since only their preview models and default scripts are different.

Properties

  • lives integer

    • number of times monster will respawn, if omitted or set zero, respawns forever.

  • spawnchance [1-100]

    • chance of monster respawning with each spawn check, generally this should be 100%

  • delaylow seconds

    • minimum time between spawn checks, in seconds

  • delayhigh seconds

    • maximum time between spawn checks, in seconds

  • spawnarea spawnAreaName

    • Ties monster to an msarea_monsterspawn (see below). Do not attempt to place monsters without monster spawns, it leads to issues.

  • killtarget triggerString

    • [optional] Triggers this entity when monster dies. (It does not remove the target the way the same property of trigger_relay does)

  • perishtarget triggerString

    • Trigger this when all lives are exhausted

  • scriptfile scriptfile

    • determines monster/NPC type see list of applicable script files

Note

Be aware that script names are cAsE sEnsItivE.

  • descriptfile scriptfile

    • [optional] As above, but seems to be required for some monsters. Generally, it's best to leave this as the FGD sets it.

  • nplayers integer - Only spawn this monster if there this number of players, or more, present (AUG2007 or later)

  • reqhp integer - Only spawn this monster if the total HP of all players on the server is above this number (AUG2007 or later)

  • title string-Change the monster's name to this (SEP2007a or later)

  • dmgmulti float-Multiply the monster's damage by this factor (must be > 1, SEP2007a or later)

  • hpmulti float-Multiply the monster's hitpoints by this factor (must be > 1, SEP2007a or later)

  • params token-string-Additional Parameters to adjust the monster. (Usage of this system is explained here.)

  • targetname targetString (used by other entities, such as ms_npcscript or trigger relay, to target the monster )

  • (angles, origin)

Params Key Details

Multiple addparams and their parameters are separated by semi-colons.

Beware, due to Hammer limitations, your total addparam string's length will need to be less than 100 characters. You can, however, split addparams with the ms_monsterspawns pass parameters property*, or the map's global addparams property.

These can also be applied, individually, to a monster when crossing a certain point in the map, by using the Scriptevent property on a trigger_once or trigger_multiple flagged triggerable by monsters, or with the msnpc_script entity.

They can also be added, globally, to all monsters, via Map Properties->Global Addparams(map_addparams), or to a specific set of monsters, via the ms_monsterspawn/msarea_monsterspawn's Pass AddParams(params)* property.

Universal Eventnames

For use with ms_npcscript, these work with most NPCs, including monsters/lure:

  • XXXX_race - where XXXX is, replace with desired race. This is buggy, and may cause issues (including crash). Common uses include: orc_race, hated_race, beloved_race, human_race. Full faction list and relations can be found here.

  • ELEMENT_immune: Where ELEMENT is, replace with desired element. Valid elements currently include: lightning, fire, poison, and cold. Using normal_immune sets all immunities to normal (including any immunities the creature might normally have).

  • fifty_armor - sets 50% damage absorption.

  • eighty_armor - sets 80% damage absorption.
  • make_invulnerable - makes monster invulnerable (godmode)
  • make_vulnerable - makes monster vulnerable
  • add_XXX_health - where XXX is use 10, 100, 500, or 1000 (untested)
  • double_health - Doubles creature's health based on current. Prefixes name with "Strong ", can be used repeatedly (but name effect stacks)
  • quad_health - Quadruplescreature's health based on current. Prefixes name with "Very Strong ", can be used repeatedly (but name effect stacks)
