Hi All,
I have only just started to play around with scripts so am learning, but I'm trying to create a horde type of attack, enemies attacking the main gate, so I have the enemies getting to the gate but cant work out how to have them identify they are within specific distance of the object and change to attack the object , I borrowed this from the forum, this gets the character to the gate. I think it was smallg - Thanks

Any help appreciated
if ai_soldier_state[e]=="idle" then

EntObjNogate = 32 -- gate entity's ID to move AI to

EntObjNo = g_Entity[e]['obj']; -- AI soldier entity number

ai_start_x[e] = g_Entity[EntObjNogate]['x'] -- gate object's X
ai_start_z[e] = g_Entity[EntObjNogate]['z'] -- gate object's Z
AISetEntityControl(EntObjNo,AI_MANUAL)
CharacterControlArmed(e)
AIEntityGoToPosition(EntObjNo,ai_start_x[e],ai_start_z[e])
else
end
end

use this https://forum.game-guru.com/outbound?url=https%3A%2F%2Fforum.game-guru.com%2Fthread%2F207801%3Fpage%3D12%23msg2538121

so your script will look like this

function scriptname_init(e)
ai_soldier_state[e]=="idle"
end

function scriptname_main(e)

if ai_soldier_state[e]=="idle" then

EntObjNogate = 32 -- gate entity's ID to move AI to

EntObjNo = g_Entity[e]['obj']; -- AI soldier entity number

ai_start_x[e] = g_Entity[EntObjNogate]['x'] -- gate object's X
ai_start_z[e] = g_Entity[EntObjNogate]['z'] -- gate object's Z
AISetEntityControl(EntObjNo,AI_MANUAL)
CharacterControlArmed(e)
AIEntityGoToPosition(EntObjNo,ai_start_x[e],ai_start_z[e])
if EntityLooking(e,EntObjNogate,150,25) == 1 then
ai_soldier_state[e]=="attack gate"
end
else
end
end

function EntityLooking(e,t,dis,v)
if g_Entity[e] ~= nil and g_Entity[t] ~= nil then
if dis == nil then
dis = 3000
end
if v == nil then
v = 0.5
end
if GetDistance(e,t) <= dis then
local destx = g_Entity[t]['x'] - g_Entity[e]['x']
local destz = g_Entity[t]['z'] - g_Entity[e]['z']
local angle = math.atan2(destx,destz)
angle = angle * (180.0 / math.pi)
 
if angle <= 0 then
angle = 360 + angle
elseif angle > 360 then
angle = angle - 360
end
while g_Entity[e]['angley'] < 0 or g_Entity[e]['angley'] > 360 do
if g_Entity[e]['angley'] <= 0 then
g_Entity[e]['angley'] = 360 + g_Entity[e]['angley']
elseif g_Entity[e]['angley'] > 360 then
g_Entity[e]['angley'] = g_Entity[e]['angley'] - 360
end
end
local L = angle - v
local R = angle + v
if L <= 0 then
L = 360 + L 
elseif L > 360 then
L = L - 360
end
if R <= 0 then
R = 360 + R
elseif R > 360 then

Thanks so much smallg, I went through your thread, bookmarked thanks,
I did try this script but I keep getting syntax errors, eof expected near end on multiple lines. I have tried to fix but am getting confused, could I ask you to comment the code you gave me so that I can learn what is doing what ?
Thanks for your patience

ok well your script code wasnt a complete script so you need to remember to rename my code to match your file name
and i made a small mistake when i copy & paste the state definition, it should read 'ai_soldier_state[e]="idle"'

function scriptname_init(e)
--set the starting state of the character(s)
ai_soldier_state[e]="idle"
end
 
function scriptname_main(e)
EntObjNogate = 32 -- gate entity's ID to move AI to
EntObjNo = g_Entity[e]['obj']; -- AI soldier entity number

--if they are idle then...
if ai_soldier_state[e]=="idle" then
 --get the gate's location 
ai_start_x[e] = g_Entity[EntObjNogate]['x'] -- gate object's X
ai_start_z[e] = g_Entity[EntObjNogate]['z'] -- gate object's Z
AISetEntityControl(EntObjNo,AI_MANUAL)
CharacterControlArmed(e)
--move to the gate
AIEntityGoToPosition(EntObjNo,ai_start_x[e],ai_start_z[e])
--if character is withing 150range and facing within 50degrees the gate then swap to attacking state
if EntityLooking(e,EntObjNogate,150,25) == 1 then
ai_soldier_state[e]=="attack gate"
end
else
end
end
 
 
--ignore below as it's a function and not directly part of the script, just called from the script
function EntityLooking(e,t,dis,v)
if g_Entity[e] ~= nil and g_Entity[t] ~= nil then
if dis == nil then
dis = 3000
end
if v == nil then
v = 0.5

Thanks again, I appreciate the time you've taken,
It was actually the function I was looking to learn from, but as you suggested to ignore it I will, I have the code not throwing any errors but nothing changes when its running, do I have to declare "ai_soldier_state[e]=="attack gate"" somewhere ?

Thanks

nothing changes because you need to put in what you want to happen in the new state - all i did was add the code to check the character is at the gate

as for the function... not sure what i can explain about it, basically it checks for the range first and then the angle of the character is within the given angle "allowance" (checking each side separately so i can adjust for the below 0 and above 360 cut off)

and yes you need to add your new state

function scriptname_init(e)
--set the starting state of the character(s)
ai_soldier_state[e]="idle"
end
  
function scriptname_main(e)
EntObjNogate = 32 -- gate entity's ID to move AI to
EntObjNo = g_Entity[e]['obj']; -- AI soldier entity number
 
--if they are idle then...
if ai_soldier_state[e]=="idle" then
 --get the gate's location 
ai_start_x[e] = g_Entity[EntObjNogate]['x'] -- gate object's X
ai_start_z[e] = g_Entity[EntObjNogate]['z'] -- gate object's Z
AISetEntityControl(EntObjNo,AI_MANUAL)
CharacterControlArmed(e)
--move to the gate
AIEntityGoToPosition(EntObjNo,ai_start_x[e],ai_start_z[e])
--if character is withing 150range and facing within 50degrees the gate then swap to attacking state
if EntityLooking(e,EntObjNogate,150,25) == 1 then
ai_soldier_state[e]=="attack gate"
end
elseif ai_soldier_state[e] == "attack gate" then
--play attack animation?
end
end

Thanks SG but this has driven me bonkers, I don't quite get how transitioning from one animation to another can be so complex (to me at least), it seems no matter what I change the entity (the armed goblin) just runs to the gate (intended), rotates around and just keeps running on the spot (definitely not intended), I used the fantasycreature script as a base, here it is in full if you feel like tackling it but I understand if its too much grief. Thanks again for trying

Not sure if this will help.

Quote: " it seems no matter what I change the entity (the armed goblin) just runs to the gate (intended), rotates around and just keeps running on the spot (definitely not intended), "

monte, it looks like you changed smallg's EntityLooking function at line 67.. in the above script..

from
if GetDistance(e,t) <= dis then -- this is the distance between entity and gate
to
if GetPlayerDistance(e,t) <= dis then -- this is the distance between entity and the player

it needs to be.. if GetDistance(e,t) <= dis then

Maybe the ai cannot get to within 150 units of the origin/centre of the gate? .
Try increasing the 150 distance value in..
if EntityLooking(e,EntObjNogate,150,25) == 1 then

[Update typo wrong function..]
Also smallg,s EntityLooking function calls for the GetDistance(e,t) function to get the distance between entity and gate, but I don't see it in the attached scripts.

Cheers

Thanks for taking a look perelect,

I did change line 67, thinking it was a typo because it keeps throwing a nil value, the area around the "gate" is unobstructed so I'm really confused as I still cant see where SG's script is calling for GetPlayerDistance(e,t) function so I didn't include it ?

Mother told me there would be days like this

Thanks, that cleared the errors, much appreciated and I see the function you added, but, you know the bit,
if ai_soldier_state[e]=="attack gate" then
-- do something -- note: FireWeapon(e) only works on the player, as far as I know, so you need to script the damage to the gate. (2)
-- force ai to keep looking at 2
-- do something like hurt(2), reposition ai, delay, hurt(2), reposition ai, delay ....

That's what has been getting me all along, I'm wanting the entity to use the attack animation to attack the gate, knowing I would have to script the gate damage but the change in state from at the gate to attacking the gate has been the biggest issue,
I have tried,

+ Code Snippet

if g_Entity[e]['animating'] == 0 then
SetAnimationFrames(160,189)
PlayAnimation(e)
  LoopAnimation(e);
  g_Entity[e]['animating'] = 1
  end

With no joy...

yep that's my mistake because i edited my original PlayerLooking() function which used GetPlayerDistance(e) so i obviously just substituted my GetDistance() function and forgot that wouldnt work if it's not included in the global, i shall fix it now so the function works on it's own as intended, thanks

i believe this is close to what you want to achieve

local damage = 30 --amount of damage each attack does to the gate
EntObjNogate = 4 -- gate entity's ID to move AI to

--if inside gate direction is to the left of map set x to negative / or positive number for right

I must thankyou both for going to a huge effort, smallg you have basically given me the script I was after, I watched your vid, and that is what I'm trying to achieve. I have added the script, made the changes required, distance, inside the gate co-ordinates and entity number and it still does not work for me, the ai doesn't stop as in line 32 and now the doors just fly open and they walk right on in.

So, I think I must have a bigger issue, no idea what but, I have just noticed that no other scripts are functioning in my scene at all, to add to it I have the "creating ai obstacles" bug so each time I test the scene it takes an eternity (feels like) to load up. I think I'm getting a message not to proceed...

I cant ask either of you for any more help than you have already given. I'm going to leave this one while I still have a small amount of sanity left

but thanks again

sorry to hear that but yh AI code is not the best place to start, it's still annoying for me when they refuse to work as expected - sometimes it's not even anything we're doing wrong.

i did forget to mention the gate health needs to be higher as they are actually attacking it and doing damage (once it reaches below 100 it will open, can't remember if there was a reason for that, i think it may just have been to make sure it didnt go below 0 and stop the script from functioning?)
