[SOLVED] Question about entity brain

[. . .]

Hello, ! 

If someone can please explain to me what these codes do because i'm trying to make my entity follow my character nicely but it moves so random because I don't know what this code means so I keep adding random numbers ... !!!

local MIN_FOLLOW_DIST = 20

local TARGET_FOLLOW_DIST = 5

local MAX_FOLLOW_DIST = 10

Follow(self.inst, GetLeader, MIN_FOLLOW, TARGET_FOLLOW, MAX_FOLLOW, true)),

 

local MAX_WANDER_DIST = 666

Wander(self.inst, GetWanderPosition, MAX_WANDER_DIST)

 

local RUN_AWAY_DIST = 10

local STOP_RUN_AWAY_DIST = 10

WhileNode(function() return self.inst.components.health:GetPercent() < 75 end, "LowHealth",
RunAway(self.inst, "jesuschrist", RUN_AWAY_DIST, STOP_RUN_AWAY_DIST)),

 

local MAX_CHASE_TIME = 0

ChaseAndAttack(self.inst, 999),

 

If someone could tell me what these things do I really would appreciate it! I'm soooo tired of messing around with random numbers not knowing what i'm doing !!!

Thank you so much for reading my question, have a wonderful day/night !!!

IIRC

Min follow: how close a following entity is allowed to be to its target

Max follow: how far an entity can be from its target before being forced to follow

Target follow: when an entity starts to follow it'll pick a position this far away from its target and move to it (when it stops or its brain updates and it is too close or too far from the target it'll adjust its position)

Max wander: how far it can wander from a known location (usually its home). Basically its able to roam anywhere in a circle centred on this location (radius of which is max wander)

Run away dist: how close something scary can get before an entity runs away

Stop run dist: when an entity starts to run it'll pick a point this far directly away and run to it

Max chase time: how long (in seconds) an attacking entity will chase a target before giving up

@chromiumboy I'm gonna have to copy & paste that in a txt file then I never forget !! I can finally understand what i'm doing!! Thank you so much kind sir!!!

 

@chromiumboy If I can just ask you 1 more question if you know please tell me if you don't then just tell me you don't !

So, my question is if I want to give some variance to my follower's follow dist & I make something like this & put it in its brain would it work?

local function RandomFollowDistance(inst)
inst:DoTaskInTime(1, function()
if math.random() > 0.50 then
inst.brain:ForceUpdate()
local MAX_FOLLOW_DIST = 1
elseif math.random() > 0.33 then
inst.brain:ForceUpdate()
local MAX_FOLLOW_DIST = 5
elseif math.random() > 0.33 then
inst.brain:ForceUpdate()
local MAX_FOLLOW_DIST = 33
end
end)
end

EDIT: It seems it doesn't work ... Would you know if something like this is possible? Maybe making my follower switch brains every couple seconds?

I don't know much about what you are trying there, but I know that using "local" for the same variable more then once in the same function is evil (also don't know why, but it will always causes errors).
so define your variable first and then write it without local before.

And try to use intendtations..
 

local function RandomFollowDistance(inst)
    inst:DoTaskInTime(1, function()
        local MAX_FOLLOW_DIST = x    -- replace x with a number of course
        if math.random() > 0.50 then
            inst.brain:ForceUpdate()
            MAX_FOLLOW_DIST = 1
        elseif math.random() > 0.33 then
            inst.brain:ForceUpdate()
            MAX_FOLLOW_DIST = 5
        elseif math.random() > 0.33 then
            inst.brain:ForceUpdate()
            MAX_FOLLOW_DIST = 33
        end
    end)
end

if you already defined the local MAX_FOLLOW_DIST elsewehere in your script, outside of a function, then of course you don't need the "...= x" line, cause it is already defined as local. (only define a variable as local once!)

edit:
just some explanation about "local":
If you write
local test = 1
in your script, outside of any function, that means that this variable "test" will be accessable in your whole script, outside and inside of your functions of that script. But it won't be accessable in other scripts of course.
If you write it instead inside of a function, that means that it will be only accessable in this specific function, not in other functions and not outside of functions.

I'm trying to make my entity be a little more random (like a player) so I want to change it's follow distance every couple seconds but it seems it doesn't work .. I tried code like this but my follower never even activates this function? Do you maybe know how I can make this function activate for my entity every 5 seconds?

local function RandomFollowDistance(inst)
    inst:DoTaskInTime(5, function()
    if math.random() > 0.50 then
    MAX_FOLLOW_DIST = 1
	MAX_FOLLOW = 1
	TARGET_FOLLOW_DIST = 1
	MIN_FOLLOW_DIST = 1
	MIN_FOLLOW = 1
	TARGET_FOLLOW = 1
	inst.brain:ForceUpdate()
	inst.components.talker:Say("Blah...")
    elseif math.random() > 0.33 then
    MAX_FOLLOW_DIST = 5
	MAX_FOLLOW = 5
	TARGET_FOLLOW_DIST = 5
	MIN_FOLLOW_DIST = 5
	MIN_FOLLOW = 5
	TARGET_FOLLOW = 5
	inst.brain:ForceUpdate()
	inst.components.talker:Say("Blah...")
    elseif math.random() > 0.33 then
    MAX_FOLLOW_DIST = 10
	MAX_FOLLOW = 10
	TARGET_FOLLOW_DIST = 10
	MIN_FOLLOW_DIST = 10
	MIN_FOLLOW = 10
	TARGET_FOLLOW = 10
	inst.brain:ForceUpdate()
	inst.components.talker:Say("Blah...")
    end
    end)
end

of course you have to call "RandomFollowDistance" at some point.
for debuggin, so seeing if the function is called, you can also add "print" statements and see the logfile if it is printet (Or hit CTRL+L while ingame and playing as host, to see the logs ingame)
