How to make an entity collide with NPC/player hitboxes, not bounding box?

[TheMostUpset]

Is there a solid flag for that or something? SOLID_NONE collides only with world, but doesn't call ENT:Touch(), others collide with anything including bounding boxes.
Next, FSOLID_MAX_BITS without setting SetSolid collides with world and world entities, calling ENT:Touch(). And for NPCs, prop_physics, players I must do a trace check in Think hook. This is kinda silly. How to set everything properly, so it hits everything BUT bounding boxes for NPCs?
Also, I don't use physics.

Just wondering if you're aware of the wiki warnings for ENT:Touch()

Ah, indeed. Any other methods without setting physics object?

[doesNootCompute]

I think you should be good if you have SetTrigger set to true, try it and let me know.

[TheMostUpset]

Nope. Collides only with world and world entities

[doesNootCompute]

I'm a bit confused, you want to collide with everything except for NPCs?

[TheMostUpset]

With everything including NPCs. But by default it collides with their bounding box instead of model hitboxes

[doesNootCompute]

I could be wrong here but I think you need to enable physics and SetSolid to SOLID_VPHYSICS

[TheMostUpset]

Even with physics it collides with bounding boxes

function ENT:Initialize()
    self:SetSolid(SOLID_VPHYSICS)
    self:SetModel(self.Model)
    self:PhysicsInitBox(Vector(), Vector())
	local phys = self:GetPhysicsObject()
	if IsValid(phys) then
		phys:EnableGravity(false)
		phys:SetVelocity(self:GetForward() * 2000)
	end
end

function ENT:StartTouch(ent)
    print(ent) -- calls on bounding box hit
end

[doesNootCompute]

I think you need to use this for physics collisions

[TheMostUpset]

Yes, but the entity still hits bounding boxes. No matter where we detect collisions.

[doesNootCompute]

You don't wanna be calling PhysicsInitBox even with a nil Vector

Then there won't be physics object. My model doesn't have physics mesh

[doesNootCompute]

Have you considered using a bounding box but editing the Hull?

[TheMostUpset]

Do you mean SOLID_BBOX with self:SetCollisionBounds()? I don't get it

[doesNootCompute]

Yes SetCollisionBounds would work for when you're using SOLID_BBOX.

This may be of use: NPC/SetHullType

[TheMostUpset]

No matter what I do, the entity always hits a bounding box. I guess, the only solution is checking hit in Think with traces. Damn.

I think the real issue is the lack of a physics mesh

[TheMostUpset]

Just tried another model with physics mesh. Same result.

[doesNootCompute]

May I see the code?

[TheMostUpset]

function ENT:Initialize()
    self:SetModel("models/props_lab/cactus.mdl")
    self:PhysicsInit( SOLID_VPHYSICS )
local phys = self:GetPhysicsObject()
    if IsValid(phys) then
        phys:Wake()
        phys:EnableGravity(false)
        phys:SetVelocity(self:GetForward() * 100)
    end
end
This is enough for tests. Am I missing something?

[hoobsug]

you better use some traces

[doesNootCompute]

AddCSLuaFile()

ENT.Base      = "base_ai"
ENT.Spawnable   = true

function ENT:Initialize()
 
  self:SetModel( "models/alyx.mdl" )
  self:PhysicsInit( SOLID_VPHYSICS )      -- Make us work with physics,
  self:SetMoveType( MOVETYPE_VPHYSICS )   -- after all, gmod is a physics
  self:SetSolid( SOLID_VPHYSICS )         -- Toolbox
 
  local phys = self:GetPhysicsObject()
  if (phys:IsValid()) then
    phys:Wake()
  end
end

Try this, pretty sure the issue was the lack of a base.

[TheMostUpset]

Well, seems like there's nothing we can do here. I'll continue using traces in Think
Thanks for your help.

Hitboxes cannot be used for collision by default; it would be extremely expensive since you're tracing rotated boxes against other rotated boxes.

[TheMostUpset]

So if I do traces every tick, how bad is it?
