 Particle check issue Ok, so, I made a brain crab and I wanted to add a nice touch to it - Instead of being just a crab with a brain sprite, I made an attachable brain that can be destroyed without the crab itself being destroyed (Realism and such, you know). Anyway, the issue is rather stupid I think, but I can't seem to solve it... >________>' So, the way the thing works is that there is an emitter attached to the attached brain, that emitter emits a MOPixel. A lua script attached to the crab checks whether the particle exists within a certain range and if it doesn't find it, the activity ends. The issue is that... Well... The activity ends, regardless whether the particle exists or not, or alternatively, the script does nothing at all. This is the code: Code: function Update(self)
local curdist = 200;
for particle in MovableMan.Particles do
local avgx = particle.Pos.X - self.Pos.X;
local avgy = particle.Pos.Y - self.Pos.Y;
local dist = math.sqrt(avgx ^ 2 + avgy ^ 2);
if particle.PresetName == "Brain Check" and dist < curdist then
self.Existing = 1
else
self.Existing = 0
end
if self.Existing == 0 then
ActivityMan:EndActivity();
else
self.Existing = nil;
end
end
end Please point out the idiotic mistake here, I really want to get this thing done. >________>'

Re: Particle check issue I thought you were able to just directly have the brain attached and have it work. Try not bothering with Lua and attaching a brain actor to the crab.

Re: Particle check issue Check running before emitter starts emitting, maybe?
Your implementation feels odd to me.
How about using lua to look at itself and see if there's a brain attached instead?
Via if there is a brain actor within a close distance, with no emitters needed.

Re: Particle check issue Code: function Create(self)
self.brainname = "name"; -- Name of brain attachable goes here
self.brainclass = "Attachable"; -- Class of brain attachable goes here
self.brain = nil;
for i = 1,MovableMan:GetMOIDCount()-1 do
target = MovableMan:GetMOFromID(i);
if target.PresetName == self.brainname and target.Class == self.brainclass and target.RootID == self.ID then
self.brain = target;
end
end
end
function Update(self)
if self.brain.ClassName ~= self.brainclass then
ActivityMan:EndActivity();
end
end Attach that to the crab.

Re: Particle check issue You can make the brain an actor attached to the crab just in ini code, and then use lua on the crab to check and see if there is a brain actor with the right Presetname within some distance from itself. Given that the brain is always near, and the mission is probably only going to have one of these guys, it should work. The activity would end if the brain ever fell off and was not broken though.
You could also script the mission itself to look for the actor brain, if it's only going to be used in one place.
Ah, ninja'ed by a better solution.

If I understanding you correctly, then that won't work. Attaching actors to other actors via .ini results in crashes during loading. @ CaveCricket Attempt to index field 'brain' (a nil value) @ line 14.

Re: Particle check issue Well shoot. Whoops.
That's a foot in my mouth. I get lua scripting, not ini code.
In that case, disregard whatever I've said.
I'll just follow the solution here and not inject fails.

Re: Particle check issue Try this: Code: function Create(self)
self.brainname = "name"; -- Name of brain attachable goes here
self.brainclass = "Attachable"; -- Class of brain attachable goes here
self.gotbrain = false;
self.brain = nil;
for i = 1,MovableMan:GetMOIDCount()-1 do
target = MovableMan:GetMOFromID(i);
if target.PresetName == self.brainname and target.Class == self.brainclass and target.RootID == self.ID then
self.brain = target;
self.gotbrain = true;
end
end
end
function Update(self)
if self.gotbrain == true then
if self.brain.ClassName ~= self.brainclass then
ActivityMan:EndActivity();
end
end
end

Re: Particle check issue Well, there don't seem to be any errors and such, there just isn't any effect.
Nothing happens when the attached brain is destroyed. >__________>'

Re: Particle check issue Whoops, it's "ClassName" not "Class". Silly me. Code: function Create(self)
self.brainname = "name"; -- Name of brain attachable goes here
self.brainclass = "Attachable"; -- Class of brain attachable goes here
self.gotbrain = false;
self.brain = nil;
for i = 1,MovableMan:GetMOIDCount()-1 do
target = MovableMan:GetMOFromID(i);
if target.PresetName == self.brainname and target.ClassName == self.brainclass and target.RootID == self.ID then
self.brain = target;
self.gotbrain = true;
end
end
end
function Update(self)
if self.gotbrain == true then
if self.brain.ClassName ~= self.brainclass then
ActivityMan:EndActivity();
end
end
end
