 Mouse position? How do I get mouse position? Something sort of finding the point where the sharp aim dots are.
As well, how do I get forward vectors of an object? And playing sounds via lua.

Re: Mouse position? Quote: How do I get mouse position? Something sort of finding the point where the sharp aim dots are.
I don't know this, although I have always been wondering about it. Quote: As well, how do I get forward vectors of an object? Do you mean how fast something is going in its direction? That would be "object.Vel.Magnitude" Quote: And playing sounds via lua.
Currently, the only way is to spawn something that would make a sound, no pure Lua method. Who ever made the base teleporters spawn an emitter with the burst sound for the sound, which seems like the simplest option to me.

Re: Mouse position? I'm meaning the from point A and the vector going to point B, I'm using this in the CastObstacleRay function.

Re: Mouse position? Code: object.Vel = Vector(pointB.X-pointA.X,pointB.Y-pointA.Y):SetMagnitude(#); Replace # with the speed you want.

Re: Mouse position? Code: function Update(self)
self.Pos = self.owner.Pos + Vector(0,-50);
self.Vel = self.owner.Vel;
if self:IsEmitting() == true then
self:EnableEmission(false);
end
--self.RotAngle = self.Owner:GetAimAngle(false);
if self.ToSettle == true then
self.toDelete = true;
self.owner.gunpodOn = false;
end
--if self.owner:IsPlayerControlled() == false then
--Fing a target not on same team
local curdist = 500;
for actor in MovableMan.Actors do
local avgx = actor.Pos.X - self.Pos.X;
local avgy = actor.Pos.Y - self.Pos.Y;
local dist = math.sqrt(avgx ^ 2 + avgy ^ 2);
if dist < curdist and actor.Team ~= self.Team then
curdist = dist;
self.target = actor;
end
end
--local targetdir = math.atan2(-(self.target.Pos.Y-self.Pos.Y),(self.target.Pos.X-self.Pos.X));
--RayDistance = SceneMan:CastObstacleRay(self.Pos, self.target.Pos, Vector(0, 0), Vector(0, 0), self.ID, 0, 5);
--TargetDist = math.sqrt((self.target.Pos.X-self.Pos.X)^2 + (self.target.Pos.Y-self.Pos.Y)^2);
--print(RayDistance);
--print(TargetDist);
if MovableMan:IsActor(self.target) then --and RayDistance >= TargetDist then
--The direction from the center of the missile to the target.
local targetdir = math.atan2(-(self.target.Pos.Y-self.Pos.Y),(self.target.Pos.X-self.Pos.X));
if targetdir ~= self.RotAngle then
self.RotAngle = targetdir;
end
if self:IsEmitting() == false then
self:EnableEmission(true);
end
else
self.HFlipped = self.owner.HFlipped;
self.RotAngle = 0;
if self:IsEmitting() == true then
self:EnableEmission(false);
end
end
--elseif self.owner:IsPlayerControlled() == true then
--self.HFlipped = self.owner.HFlipped;
--end
--If owner is dead, gib self.
if self.owner:IsDead() == true then
self.ToDelete = true;
end
end I'm basically doing a helper gunpod, but I'm trying to get it so that it can only shoot at what it can "see" hence the want for the castobstacleray, I need it to check if there's anything between the target and the gunpod. So it won't shoot though walls, shoot the owner...

Re: Mouse position? A StrengthRay would work in place of an ObstacleRay. This would work for you: Code: local terrcheck = Vector(0,0);
if not(SceneMan:CastStrengthRay(self.Pos,Vector(self.target.Pos.X-self.Pos.X,self.target.Pos.Y-self.Pos.Y):SetMagnitude(500),0,terrcheck,3,0,true)) then

Re: Mouse position? Alright works, but why not ObstacleRay? Just wondering.

Re: Mouse position? No real reason, just that I have no experience with ObstacleRays. BTW, I thought about this a little bit at school, and you should try: Code: local terrcheck = Vector(0,0);
if not(SceneMan:CastStrengthRay(self.Pos,Vector(self.target.Pos.X-self.Pos.X,self.target.Pos.Y-self.Pos.Y),0,terrcheck,3,0,true)) then The previous version would cast the ray too long and the turret may not fire at enemies in front of walls.

Re: Mouse position? Works better, but it doesn't seem to check if the owner is between it and the target, had it eat the head off... Is it good to use a MORay with it? So if the parent's ID is returned...

Re: Mouse position? Yes, MORays would work too. Be sure to set the "material ID to ignore" to 0.

Re: Mouse position? Working on another lua based weapon now, what's the property name for MOSRotatings in the moveable manager?

Re: Mouse position? MovableMan.Particles, and then check for if particle.ClassName == "MOSRotating"

Re: Mouse position? What if I want to run a function like GibThis(); How does type casting happen in lua?

Re: Mouse position? I'd do
for particle in MovableMan.Particles do
if particle.ClassName == "MOSRotating" then
<insert supplementary checks here>
mosr = ToMOSRotating(particle);
mosr:GibThis();
end
end

Re: Mouse position? Hrm funky, no errors, but I'm trying to get this to gib pretty much any object that's a subclass of MOSRotatings, so far its doing nothing. Code: function Create(self)
local curdist = 33;
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 dist < curdist and (particle.ClassName == "MOSRotating") then
mosr = ToMOSRotating(particle);
mosr:GibThis();
end
end
end
function Update(self)
local curdist = 33;
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 dist < curdist and (particle.ClassName == "MOSRotating") then
mosr = ToMOSRotating(particle);
mosr:GibThis();
end
end
end
