Entity placing inside prop.

[Ol' Reaper]

So I am trying to make a SWEP were you can place a C4 on a prop or door and it will blow it up but the model I am using have the center point in the center of the model so when I use the following code:

local tr = ply:GetEyeTrace()
bomb = ents.Create("bomb_ent")
bomb:SetPos(tr.HitPos)
bomb:SetAngles( tr.Entity:GetAngles() )
bomb:Spawn()
bomb:SetParent(tr.Entity)

It will place half the model inside the prop and the other half outside it.
On the left is how I want it to be but on the right is how it spawns. How can I make it "retract" by a couple of units?

I'm not sure but try changing the code around like this:

local tr = ply:GetEyeTrace()
bomb = ents.Create("bomb_ent")
bomb:SetPos(tr.HitPos)
bomb:SetAngles( tr.Entity:GetAngles() )
bomb:SetParent(tr.Entity)
bomb:Spawn()

This could be completely wrong but I don't have a lot of experience with entity coding.

I swapped the parent and spawn code around so that the parent is set prior to the spawn. I'll see if I can figure it out, I'll keep checking this thread :)

It's not that I don't think as when I removed the parent part and made it just freeze it was still the same.

Hmm, I'm not really sure but you could try:

 SetPos(tr.HitPos + 5) -- Add 5 to the entity's position

This could be completely wrong but it's worth a shot right? I'll see if I can find any information about this.

[find me]

[lua]
local tr = pl:GetEyeTraceNoCursor()
local prop = ents.Create("prop")
prop:SetModel(arg[1])
prop:SetPos( tr.HitPos + (tr.Normal*-1) * (prop:OBBCenter().x-prop:OBBMins().x) )
prop:SetAngles( tr.HitNormal:Angle() )
prop:Spawn()
[/lua]

tr.HitNormal returns the [I]vector direction[/I] of the surface you hit, use "Angle()" to convert to an angle. (tr.HitNormal:Angle())

tr.Normal returns the direction from trace start to trace end. Reverse that to get the "retract" direction you desire your entity to move. (tr.Normal*-1)

You only want to "retract" the entity half of its overall width, considering it spawns in the center. Take the entity center point, and the bottom corner point. Extract the x length between the two. (prop:OBBCenter().x-prop:OBBMins().x)

And that's me completely lost :what: :goodjob:

Thanks find me. It works.
