 AAI help..... Hello, I am currently working on trying to make an Lua-file to work the way it is supposed to but have struck a hard end as the script doesnt work..... Now i am turning here to ask for help to make it work..... AAI, Advanced Artificial Intelligence, was supposed to make units search for the closest enemy unit and then give a GO-TO command to it..... Code: function Create(self)
self.Target = nil;
self.Target1 = nil;
AIMode = 3;
Dist = 100;
if self.Team == 0 then
self.EnemyTeam = 1;
else
self.EnemyTeam = 0;
end
end
function Update(self)
self.Target = MovableMan:GetClosestActor(self.EnemyTeam, self.Pos, 500, Dist, self);
if MovableMan:IsActor(self.Target) and MovableMan:IsActor(self.Target1) then
if self.Target.ID ~= self.Target1.ID then
self.Target1 = self.Target;
self:ClearAIWaypoints();
self:AddAIMOWaypoint(self.Target1);
end
end
end So please, if anybody could help me i would be really grateful.

end
end The rest looks like perfectly good code to me.

Re: AAI help..... Theory sucks, just like physics. WHY CAN'T I BE A FRICTIONLESS SURFACE.

Re: AAI help..... Actually, his original way of determining enemy team was far better. It's more efficient. There's no reason to run through every actor in the game just to determine the team. What if there are no other actors? Then the method won't work. Your method isn't going to allow it to work on team -1, either. Remember, this is being run in the Create function, so it only happens once. It's only going to return one number. However, this would be a better way of working the code: Code: function Create(self)
self.Target = nil;
self.Target1 = nil;
AIMode = Actor.AIMODE_GOTO;
Dist = 100;
if self.Team == Activity.TEAM_1 then
self.EnemyTeam = Activity.TEAM_2;
else
self.EnemyTeam = Activity.TEAM_1;
end
for actor in MoveableMan.Actors do
if self.Team ~= actor.Team then
EnemyTeam = actor.Team;
end
end
end
function Update(self)
self.Target = MovableMan:GetClosestActor(self.EnemyTeam, self.Pos, 500, Dist, self);
if MovableMan:IsActor(self.Target) and MovableMan:IsActor(self.Target1) then
if self.Target.ID ~= self.Target1.ID then
self.Target1 = self.Target;
self:ClearAIWaypoints();
self:AddAIMOWaypoint(self.Target1);
end
end
end It's always best to use constants instead of "magic numbers". Now, as for the problem... I did some testing with MovableMan:GetClosestActor and I can't for the life of me get ClosestActor working. Try ClosestTeamActor again, but I'm pretty sure this is another case of function implementation that is incompatible with Lua (it's looking for pointers, but Lua doesn't have explicit pointers). I think your best bet would be to use the code from the homing missile to find the nearest actor. It's not as efficient as using a built-in function, but I don't think this function is even working.

Re: AAI help..... Actually, as far as I can tell, that function doesn't exist as of B23. Correct me if I'm wrong, but I'm unable to call it up.

Re: AAI help..... I never knew function Create only ran once, good to know, good to know.
I meant to put it in Update...
But I guess that would be a little slower than doing what he did before, seemed to work fine in my code though.
