[WalkingZombie]

I would like to put a halo around an SENT. I have code that's using 'self'. I had it working in the think function, but it's not good to do that. This is the code I was using:
[lua] if !self then return end local Fluxor = math.tan(CurTime()*8)
if Fluxor > 2 then Fluxor = 0 end
local Flux = .5*Fluxor
Flux = math.max(0.1, math.Clamp((Flux*.9)+.1, 0, 1))
halo.Add( {self}, Color( 0, 0, 0, 255 ), 10, 10, 1, false, false )
halo.Add( {self}, Color( 255, 128, 0, 255 ), 10*Flux, 10*Flux, 1, true, false )[/lua]
I'm trying to use hook "PreDrawHalos" to run this code. Of course, that doesn't work, so how can I fix this problem?

[Kogitsune]

You could do something like this on the client for your SENT.

function ENT:Initialize( )
  hook.Add( "PreDrawHalos", self, self.PreDrawHalos )
end

function ENT:PreDrawHalos( )
  local tr = { }
  local pl = LocalPlayer( )

  tr.start = pl:GetShootPos( )
  tr.endpos = tr.start + pl:GetAimVector( ) * 100
  tr.filter = pl

  tr = util.TraceLine( tr )
  
  if tr.Entity == self then
    halo.Add( { self }, Color( 160, 0, 192 ), 1, 1, 10 )
  end
end

[WalkingZombie]

I don't want it to apply the same for every one, I will want to make it disappear when one of the ENT's variables runs down to 0. This variable, however, has a different value for every player. I will script it so when the table var is 0 for the LocalPlayer() the halo will not draw. Because of this it needs to be the self, and not every instance.

Instead of using a trace, you can always just check the conditions

if < some set of conditions > then
  halo.Add( < relevant data > )
end

You'd have access to the player via LocalPlayer and everything.

Oh... ok well you've answered one of the questions I had in the back of my mind. That code isn't exactly what I planned on doing, but I should be able to make it work now! Thank you for the help!

The table is set server side, so I believe I'll need to network it.

The colon is used for calls and declarations where the OOP aspect is needed. The actual function is accessed with the period.

Call
[lua]ENT:Function()[/lua]

Declaration
[lua]function ENT:Function()

end[/lua]

Access
[lua]local func = ENT.Function[/lua]

Trying to access it using a colon won't work.

It has been a bit since I messed with it, but it used to be ( and may still be ) that if you created the physics with PhysicsInitBox/Sphere without setting the model first, it'd be solid for movement but wouldn't block traces / bullets - which isn't desirable because we want to be able to trace to it.

Other than that, there isn't a way that isn't terribly hacky - like checking for bullets being shot and having your entities fake being not solid for a frame or two, but that would cause all kinds of problems.

The best way would be to ask whoever adds engine methods to define Entity:SetSolidMask( int mask ) since it is hard coded for CBaseEntity to return SOLID_MASK in physics_main_shared.cpp:

unsigned int CBaseEntity::PhysicsSolidMaskForEntity( void ) const
{
    return MASK_SOLID;
}

You could use [URL="http://wiki.garrysmod.com/page/GM/EntityFireBullets"]GM:EntityFireBullets( Entity ent, table data ) [/URL]

When something fires a bullet, do a trace to see if your fence prop is the only thing in the way and fire a new bullet from the other side of the fence along the same normal.

or

make a custom entity (i.e. "prop_fence"), the entity when shot fires a new bullet along the hit normal from the other side.

just a few thoughts, hope it helps.

[ROFLBURGER]

Oh well.

Now I have another question, is there a way to check if prop is in a player?

ent:GetPhysicsObject():IsPenetrating() only checks if another prop is in it

unfortunately I can't do this because it needs to be a prop_physics in order for all this to work

[Kogitsune]

Create an entity that is 30 x 30 x 70, make it a non-solid trigger parented to the player and centered so it is just inside the player object and define StartTouch and EndTouch. Have a table on the entity that is updated with each touching entity as the key in the Start/End events.

Something like:

function ENT:Initialize( )
  self.Touchers = { }
  --set bounds
  self:SetSolid( SOLID_NONE )
  self:SetTrigger( true )
end

function ENT:StartTouch( e )
  if e ~= self:GetParent( ) then
    self.Touchers[ e ] = true
  end
end

function ENT:EndTouch( e )
  self.Touchers[ e ] = nil
end

Then, you would do this:

SafeRemoveEntity( pl.Checker )
pl.Checker = ents.Create( "collision thing name here" )
pl.Checker:SetPos( pl:GetPos( ) + vector_up )
pl.Checker:SetParent( pl )

pl.IsIntersecting = function( me, that )
  if not IsValid( me.Checker ) then
    return false
  end

  return me.Checker.Touchers[ that ]
end

There's probably a better way, but I don't think there's a way other than looping through all entities and doing manually doing a box within box collision check.

[QUOTE=sacred1337;46420703]I'm trying to make an entity do a 2D orbit. at a set height (Z)
Circle math isn't my thing, but this is what I've got :P

This is what im doing, the movement works, alothough it's pretty rubberbandy until it gets into a nice circle (rubber bands as it hits the path).
If you've got better ideas for the movement, i'd appreciate it.

The Angle is more my issue, this seemed to work but then just goes random, it seems to sometimes try and align itself but is pretty horrible at it.
[/QUOTE]

An easy way is to simply use an _ang = Angle( 0, 0 , 0 ) ( modify yaw ) then _ang.y = math.NormalizeAngle( _ang.y );
Then use the forward normal: _ang:Forward( ), then use a start position plus the normal plus the distance away. _p:GetPos( ) + angle:Forward( ) * 50;

Now, it will orbit around the player if you simply keep incrementing yaw on the angle. It is an easy way to have a 2d orbit.

If you want to stick a camera on the orbit, and have the orbit face the center simply invert the angle ( add 180 to yaw and it'll face the center ). Here's my over-the-shoulder thirdperson free camera: [url]https://dl.dropboxusercontent.com/u/26074909/tutoring/camera/cl_thirdperson_freecam.lua.html[/url]

Orbits using Forward( ) * -1 to start behind, also instead of orbiting by just incrementing by 1 I simply use the direction the player is looking in ( which also means I don't need to reverse the angle to get it to look at the player ).

I'm drawing a laser with render.DrawBeam() from everyones eyes to see where they aim, it all works however the laser is going on forever until it hits something,

how can i add limit in there, so instead of waiting until the laser hits something its always at lets say 300 units?

[lua]

local tracer = Material( "sprites/physbeam" )

function test()
for k,v in pairs(player.GetAll() ) do
if ( v:Alive() && v != LocalPlayer() ) then

local trace = v:GetEyeTrace()
local start = trace.StartPos
local hit = trace.HitPos

cam.Start3D( EyePos(), EyeAngles() )
render.SetMaterial( tracer )
render.DrawBeam( start, hit, 3, 0, 0, Color( 50, 255, 50, 255 ) )
cam.End3D()

end

end

end
hook.Add("HUDPaint", "test", test)

Any help is appreciated.

this won't work since the hook isn't called with the entity as the first variable (or any variable for that matter)

edit: apparently I am wrong,
you learn something new everyday!

[Acecool]

You need a different trace, where you define the startpos and endpos.

local _p = LocalPlayer( );
local _trdata = {
	start = _p:GetShootPos( );
	endpos = _p:GetShootPos( ) + _p:GetShootPos( ) + _p:GetAimVector( ) * 300;
};
local _tr = util.TraceLine( _trdata );	

Setup mask / filter, or whatever else.... Take a look at the structure: [url]http://wiki.garrysmod.com/page/Structures/Trace[/url]

Actually, it is almost being set up correctly; it would almost be correct if it was hook.Call instead of hook.Add, but for hook.Call instead of using self as the table ( because the function self.PreDrawHalos is already being defined as the 3rd arg ) you'd need to use GAMEMODE as it is a GM hook.

For it to work, it'd need to be hook.Add( "PreDrawHalos", "NameOfHookPlusUniqueAddition" .. self:EntIndex( ), self.PreDrawHalos ); and then it'd work using function ENT:PreDrawHalos, for each entity that is added...
