Hello,

I'm trying to use together two scripts. One is by Smallg (civilian.lua) and another that showed GubbyBlips https://forum.game-guru.com/thread/223595#msg2648268

The scripts are the following:

1)

-- LUA Script - precede every function and global member with lowercase name of script

-- globals
local aniplaying = 0
ai_newdest_time = {}
ai_cover_on = {}
-- init when level first runs
function civilian_init(e)
ai_soldier_state[e] = "patrol";
ai_soldier_pathindex[e] = -1;
ai_start_x[e] = nil
ai_starting_heath[e] = nil
ai_ran_to_cover[e] = 0
ModulateSpeed(e,1.0)
ai_old_health[e] = 0
--CharacterControlStand(e)
ai_returning_home[e] = 0
ai_newdest_time[e] = -1
ai_cover_on[e] = 0
ai_alerted_spoken[e] = 0

end

function civilian_main(e)
EntObjNo = g_Entity[e]['obj'];
MoveUp(e,1)
-- Detect player distance (note: possible optimization here)
PlayerDX = g_Entity[e]['x'] - g_PlayerPosX;
PlayerDY = g_Entity[e]['y'] - g_PlayerPosY;
PlayerDZ = g_Entity[e]['z'] - g_PlayerPosZ;
PlayerDist = math.sqrt(math.abs(PlayerDX*PlayerDX)+math.abs(PlayerDY*PlayerDY)+math.abs(PlayerDZ*PlayerDZ));

--if ai_ran_to_cover[e] ~= 1 then
-- Always looking at player
--if PlayerDist < 200 then
--LookAtPlayer(e)
--AIEntityGoToPosition(EntObjNo,g_Entity[e]['x'],g_Entity[e]['z'])
--else
-- Patrol Mode
if ai_soldier_state[e] == "patrol" then

-- Try and find a close path to patrol, just check once for it
if ai_soldier_pathindex[e] == -1 then

ai_soldier_pathindex[e] = -2

CharacterControlArmed(e)

-- find initial waypoint path to follow
PathIndex = -1;
pClosest = 99999;
for pa = 1, AIGetTotalPaths(), 1 do
for po = 1 , AIGetPathCountPoints(pa), 1 do
pDX = g_Entity[e]['x'] - AIPathGetPointX(pa,po);
pDZ = g_Entity[e]['z'] - AIPathGetPointZ(pa,po);
pDist = math.sqrt(math.abs(pDX*pDX)+math.abs(pDZ*pDZ));
if pDist < pClosest and pDist < 200 then
pClosest = pDist;
PathIndex = pa;
end
end -- po
end -- pa

-- follow found path
if PathIndex > -1 then
ai_soldier_pathindex[e] = PathIndex;
ai_path_point_index[e] = 2
ModulateSpeed(e,1.0)
SetCharacterToWalk(e)
ai_path_point_direction[e] = 1
ai_path_point_max[e] = AIGetPathCountPoints(ai_soldier_pathindex[e])
end

end
-- If we have a path then lets patrol it
if ai_soldier_pathindex[e] > -1 then

ai_patrol_x[e] = AIPathGetPointX(ai_soldier_pathindex[e],ai_path_point_index[e])
ai_patrol_z[e] = AIPathGetPointZ(ai_soldier_pathindex[e],ai_path_point_index[e])

AIEntityGoToPosition(EntObjNo,ai_patrol_x[e],ai_patrol_z[e])

tDistX = g_Entity[e]['x'] - ai_patrol_x[e]
tDistZ = g_Entity[e]['z'] - ai_patrol_z[e]

DistFromPath = math.sqrt(math.abs(tDistX*tDistX)+math.abs(tDistZ*tDistZ))

if DistFromPath < 50 then
if ai_path_point_direction[e] == 1 then
ai_path_point_index[e] = ai_path_point_index[e] + 1
if ( ai_path_point_index[e] > ai_path_point_max[e] ) then
ai_path_point_index[e] = ai_path_point_max[e] -1
ai_path_point_direction[e] = 0
end
else
ai_path_point_index[e] = ai_path_point_index[e] - 1
if ( ai_path_point_index[e] < 1 ) then
ai_path_point_index[e] = 2
ai_path_point_direction[e] = 1
end
end
end
else
CharacterControlFidget(e)
end
end

-- end
--if g_Entity[e]['health'] < 100 then
-- SetCharacterToRun(e)
-- ModulateSpeed(e,1.3)
-- ai_ran_to_cover[e] = 1
-- AISetEntityControl(EntObjNo,AI_MANUAL);
-- AIEntityMoveToCover(EntObjNo,g_PlayerPosX,g_PlayerPosZ);
-- end
end

function npc_approaching3_main(e)

end
else
approachplr[e] = 0
AIEntityStop(g_Entity[e]['obj']) -- deactivate this line and AI walks to last player position!
end

if approachplr[e] == 1 then
LookAtPlayer(e)
RotateToPlayer(e)
SetCharacterToWalk(e) -- new edit
AIEntityGoToPosition(g_Entity[e]['obj'],g_PlayerPosX,g_PlayerPosZ) -- new edit
end

if idletalk[e] == 1 then
idletalk[e] = 0
Prompt("Hello, how may I help you?", 5000)
if playingsound[e] == 0 then
PlaySound(e,1);
playingsound[e] = 1
end
end -- idletalk

end -- main

In practice, the npc character should follow the waypoints in a neutral way until the player is at some distance away from him, then the second script should activate (walk towards the player and say something). I can't get them to work together because there is a conflict where the npc character is still trying to follow waypoints.

Anyone know a way to merge the two scripts? I don't know how to stop and then resume walking along the waypoints.

In another way, is it possible to write a script of this type, that executes the others:

if GetPlayerDistance(e) > 800 then

(switchscript or do file ...)

if GetPlayerDistance(e) < 800 then

(switchscript or do file ...)


Thank you in advance

that should work but you would need to assign it to another entity and pass the desired entity number cos it will swap from that script to the other script if assigned to the actual character
not really used switchscript myself but i think you have to 'require' the intended script(s) and then you can switch to it as needed

Thank you Smallg for your reply, but I'm very newbye to lua scripting. I've seen these threads: https://forum.game-guru.com/thread/217896#msg2577455 and https://forum.game-guru.com/thread/219096#msg2592310 but I don't know how to use them.
May you show me how to attach to an entity a script that controls the state of a NPC based on the distance of a player? So the NPC changes state (script) without conflicts?

it should be something like this but i'm not sure how to require a concatenated string - seems to return an error
(also not sure switch script even works in max)

@ smallg


Try this one below rather than "Require" statement.

Thank you very much Smallg and 3com. How to use Include(dbsc.behaviour2) and where, instead of:

require "scriptbank\\"..(dbsc.behaviour1)
require "scriptbank\\"..(dbsc.behaviour2)
dbsc.state = "init"

About you, is it possible to run the scripts separately from two different trigger zone that point to the NPC, and how? These types of scripts might be used in different situations.

Yep does but you have to 'require' whichever scripts you may be likely to switch to and you can't do the require in the middle of a function like that.

yh Include instead of require works, thanks
place this on an entity and make sure you have at least one entity in your map with the name you set in the behaviour

@ smallg
Nope, thanks to you for writing the script.

Thank you all! I will try to use the script.
