 More Lua Trouble I decided to mess around with some Sparkle Magic, and came up with this script. It is designed to animate a nearby gun until a certain frame, and then create some speeding particles at the said gun's position. Took me a while to iron the bugs out (believe me, there was a lot of them), and yet I can't make it work. It gives out no error, but, if I fire the gun, the game freezes instantly. Can anyone explain why? (Sorry for the lousy tabbing.) Code: function Create(self)
print ("IMMA FIRIN' MAH LAZOR!!!");
self.timer = Timer();
self.HasMOGun = 0;
self.GunTOShoot = nil;
self.GunHolder = nil;
end
function Update(self)
if self.HasMOGun == 0 then
for mo in MovableMan.Particles do
for i = 1, MovableMan:GetMOIDCount() - 1 do
mo = MovableMan:GetMOFromID(i)
if mo.PresetName == "Vocal-0-ID" then
local avgx = mo.Pos.X - self.Pos.X;
local avgy = mo.Pos.Y - self.Pos.Y;
local maindist = math.sqrt(avgx ^ 2 + avgy ^ 2);
if maindist < 100 then
if mo.ID ~= mo.RootID then
self.GunToShoot = ToAttachable(mo);
for modude in MovableMan.Actors do
modude = MovableMan:GetMOFromID(self.GunToShoot.RootID);
self.GunHolder = ToActor(modude);
end
else
self.ToDelete = true;
end
end
end
end
end
self.HasMOGun = 1;
end
while self.GunToShoot.Frame < 38 do
if self.timer:IsPastSimMS(370) then
self.GunToShoot.Frame = self.GunToShoot.Frame + 1;
self.timer:Reset()
else
self.Boom = CreateAEmitter("Sonic Burst Heavy");
self.Marker = CreateMOPixel("Sonic Burst Pixel Normal Heavy");
local theta = ToActor(self.GunHolder):GetAimAngle(true);
self.Marker.Pos = self.GunHolder.Pos + Vector(math.cos(theta)*100,math.sin(theta)*-100);
self.Boom.Pos = self.GunHolder.Pos + Vector(math.cos(theta)*50,math.sin(theta)*-50);
self.Boom.Vel = (self.Boom.Pos - self.Marker.Pos) * 0.1;
MovableMan:AddParticle(self.Boom);
self.ToDelete = true;
end
end
end

Re: More Lua Trouble So, what's running this script?

Re: More Lua Trouble A particle, created when the weapon shoots. I may be illiterate in Lua, but not so much as to try to add a script to an attachable.

Re: More Lua Trouble Only had a quick look at it but that while-loop perhaps? The timer must pass 370ms 38 times for it exit so it looks to me like it will run indefinitely.
Some other things: Why are you iterating through all particles? If the script is attached to a particle you already know the position. I would recommend using Sunshines(?) method of finding an actor; spawn the bullet inside the gun and use SceneMan:GetMOIDPixel in the Create function.

Re: More Lua Trouble My method: just fire a particle with a velocity of 1. Its Create script uses either its velocity (if it's an MOPixel or MOSParticle) or its RotAngle (if it's a MOSRotating or anything based off of it) to cast a ray backwards, which should find the weapon.

Re: More Lua Trouble Abdul: Dang. Hadn't realised that. Will try to fix it now.
Darlos: That's actually a very good idea. I'll implement it if my script starts to cause too much lag.

Re: More Lua Trouble More stuff happened. (DOUBLE POST I KNOW SORRY DON'T KILL ME) After fixing pretty much everything that needed to be fixed, I ended up with this: Code: function Create(self)
print ("Gun sequence initiated.");
self.timer = Timer();
self.HasMOGun = 0;
self.GunToShoot = nil;
self.GunHolder = nil;
self.FrameToGun = 0;
end
function Update(self)
if self.HasMOGun == 0 then
for mo in MovableMan.Particles do
for i = 1, MovableMan:GetMOIDCount() - 1 do
mo = MovableMan:GetMOFromID(i)
if mo.PresetName == "Vocal-0-ID" then
local avgx = mo.Pos.X - self.Pos.X;
local avgy = mo.Pos.Y - self.Pos.Y;
local maindist = math.sqrt(avgx ^ 2 + avgy ^ 2);
if maindist < 100 then
if mo.ID ~= mo.RootID then
self.GunToShoot = ToAttachable(mo);
print ("Weapon found: " .. self.GunToShoot.PresetName .. " Number: " .. self.GunToShoot.ID);
for modude in MovableMan.Actors do
modude = MovableMan:GetMOFromID(self.GunToShoot.RootID);
self.GunHolder = ToActor(modude);
print ("Actor found: " .. self.GunHolder.PresetName);
self.HasMOGun = 1;
end
else
self.ToDelete = true;
end
end
end
end
end
end
local GunToFrame = self.GunToShoot.Frame;
if GunToFrame < 37 then
if self.timer:IsPastRealMS(37) and self.FrameToGun < 38 then
-- print ("Current frame: " .. self.GunToShoot.Frame);
-- print ("increasing frame by 1.");
self.GunToShoot.Frame = self.FrameToGun;
self.FrameToGun = self.FrameToGun + 1;
self.timer:Reset()
end
else
self.Boom = CreateAEmitter("Sonic Burst Heavy");
self.Marker = CreateMOPixel("Sonic Burst Pixel Normal Heavy");
local theta = ToActor(self.GunHolder):GetAimAngle(true);
self.Marker.Pos = self.GunHolder.Pos + Vector(math.cos(theta)*100,math.sin(theta)*-100);
self.Boom.Pos = self.GunHolder.Pos + Vector(math.cos(theta)*50,math.sin(theta)*-50);
self.Boom.Vel = (self.Boom.Pos - self.Marker.Pos) * 0.1;
MovableMan:AddParticle(self.Boom);
print ("Adding particle: " .. self.Boom.PresetName);
print ("IMMA FIRIN' MAH LAZOR!!!");
self.ToDelete = true;
end
end The actor/gun finding part is ok, all the print lines return the correct PresetNames, but the actual effect on the gun is far from perfect. When the fire key is pressed, the gun begins animating. The frames, although, keep resetting to the first one before advancing, creating an ugly, jagged animation. Surprisingly, if there are too many MOIDS in-game, the simulation will freeze for a couple of seconds, and then animate perfectly right, without the repeated frames. Plus, the frame check in the end always returns a zero, no matter which frame the gun is displaying. The particle it is supposed to create also appears only sporadically, sometimes at the right frame, sometimes right when you press the trigger. I suspect i'm running into some kind of hardcoded barrier, but I've got a whole 38 frames of animation and want to use them all, thank you. So, anyone got ideas on how to solve this?

Re: More Lua Trouble Particles like hdfirearms and mosparticles constantly try to reset their frames. It's extremely difficult (impossible) to get them to consistently animate with Lua when they're not set to do so by .ini code.

Re: More Lua Trouble Dang again. So I reckon it would require some fidgeting with the animmode and duration, right? I am unsure on how to proceed, though, as setting the animmode to 4 only lets it animate the first frames.

Re: More Lua Trouble Uh.
Short of using guns with spinup, hdfirearms are hardcoded to only animate into their first and second frames "naturally", meaning that you're SOL, at least insofar as using an actual gun to do your animation.

Re: More Lua Trouble Grif wrote: hdfirearms are hardcoded to only animate into their first and second frames "naturally". Not quite. Using AnimMode = 4, I was able to make another gun show a whole five frames when shooting. And spinup doesn't help anyway, as it always makes the animation play several times in a row, no matter what the duration variables are set to. Oh well, I guess I'll just follow your advice and transform the gun in a pseudo-attachable, then.
