 Re: Cortex Command Lua Scripting Tutorial Quote: Code:
local varA = 5
local varB = varA
This would make variable "varB" equal to 5. Note how the word "local" was not used when recalling the variable "varA". It does use "local" when recalling variable "VarA". Quote: -- Statement checking if the distance check (variable "local distcheck") is less than 10. If so, then do the action...
if distcheck < 30 then
Two different values.

Re: Cortex Command Lua Scripting Tutorial Major, I'm pretty sure what he meant by the first one is that it shouldn't be written out as this: Code: local varB = local varA

Two different values. Yeah fixed. Also, I added another example, which is for a missile. Check it out!

Re: Cortex Command Lua Scripting Tutorial Quick question regarding tables; is there any easy way of checking whether something is in a given table? Or do i just have to "brute force" check? (as in, do a secondary for loop that checks every single entry for the variable i'm looking for)
It would be supremely useful for making a decent railgun.

Pretty much anything can be an index in Lua, so you can use a separate table to store and look up the index of the first table. Code: function Create(self)
gAct = {}
gLookup = {}
gAct[1] = self
gLookup[self] = 1
end
function Update(self)
print(gAct[gLookup[self]])
end
If "self" is not a member of "gAct" the call "gLookup[self]" will return "nil".

Re: Cortex Command Lua Scripting Tutorial thanks Abdul Alhazred. another thing(sorry) this is in my mission code. i want the player to kill all enemies and then kill the brain. for some reason it wont work. can someone tell me whats wrong? Code: -----------------------------------------------------------------------------------------
-- Update Activity
-----------------------------------------------------------------------------------------
function Battle:UpdateActivity()
-- Clear all objective markers, they get re-added each frame
self:ClearObjectivePoints();
self:Killcheck();
self:DestroyBrain();
-- Check for defeat conditions
self:DoBrainSelection();
self:YSortObjectivePoints();
end
-----------------------------------------------------------------------------------------
-- Kill Everyone check
-----------------------------------------------------------------------------------------
function Battle:Killcheck()
if self.Killcomplete == false then
print ("Kill Humans");
else
print ("Complete");
end
-----------------------------------------------------------------------------------------
-- Kill Everyone
-----------------------------------------------------------------------------------------
function Battle:KillHumans()
for Act in MovableMan.Actors do
if Act.Team ~= Activity.TEAM_1 then
self.Killcomplete = false;
else
self.Killcomplete = true;
break -- stop looping
end
end
end
-----------------------------------------------------------------------------------------
-- Destroy Brain
-----------------------------------------------------------------------------------------
function Battle:DestroyBrain()
if self.Killcomplete == true then
if MovableMan:IsActor(self.CPUBrain) then
self:AddObjectivePoint("Destroy!", self.CPUBrain.AboveHUDPos, Activity.TEAM_1, GameActivity.ARROWDOWN);
else
self.WinnerTeam = Activity.TEAM_1;
ActivityMan:EndActivity();
end
end
end

Re: Cortex Command Lua Scripting Tutorial Your KillHumans function is not being initiated in the Update function.

Re: Cortex Command Lua Scripting Tutorial that is further down, I didnt want to put my entire script in the post. what doesnt work is the mission objectives. the self:Killcheck(); and self:KillHumans(); dont work, and so self:DestroyBrain(); is never activated, and the mission cant be won. I could take out the kill functions, but I want the objective to be to kill every one, then kill the brain.

Re: Cortex Command Lua Scripting Tutorial Have you looked in the console for errors? KillChek is missing and end, and KillHumans will set self.Killcomplete to true if there are any actors on team one in the scene. Try doing it like this instead: Code: function Battle:KillHumans()
self.Killcomplete = true
for Act in MovableMan.Actors do
if Act.Team ~= Activity.TEAM_1 then
self.Killcomplete = false
break -- stop looping
end
end
end
