Prop_Physics balloon-like movement

[Black Sheep]

Alright, So I am a modeller for a guy's surf map project and I made this abstract ball of light for it. The problem is he wants the ball to be hit around the room like a balloon. I have tried a lot of mass scale changes from .0001 to 100000 and a lot of qc file changes. The balls size has a radius of 105 units and is pictured below. So my question is can anyone give me the proper properties and qc file to make a prop_physics act like a balloon?

Here is my qc file

Code: Select all

$modelname "BSmodels\BS_Sphere"
$model "BS_Sphere" "..\BS_Sphere.smd"
$cdmaterials "models\BSmodels"
$hboxset "default"
$hbox 0 "null" -105.000  -105.000  -105.000  105.000  105.000  105.000
$surfaceprop "default"
$keyvalues  { prop_data { "base" "Plastic.Small" "health" "0" "physicsmode" "1"  } }
$sequence idle "..\BS_Sphere.smd" fps 30.00
$collisionmodel "..\BS_Sphere.smd" {

   $mass 55.0
   $inertia 1.00
   $damping 0.00
   $rotdamping 0.00
}

Like, the ability to float into the air?

If so, I have an idea:
Fill the playable area with a trigger_vphysics_motion. Use a filter so it only affects your balloon(make sure to also set the proper flags in the trigger).

Set ""SetLinearForceAngles" pointing upwards and "SetLinearForce" to what ever amount is needed to push the balloons up.


If you mean something like, a "bouncing" property, then I have no idea.

Yea, That seams like it would work. However I cannot get to the trigger_vphysics_motion entity. I tried the default and a custom fdg, but no luck. I also tried manually typing it in and manually adding the keyvalues but that also did not work. Is this entity still available?

This is what I found.

VDC: (trigger_vphysics_motion)

Availability

This brush-based entity is available in: HL2. In code it is represented by class CTriggerVPhysicsMotion, defined in triggers.cpp.

Someone questions why it's only in the HL2 FGD in the discussion, but that's it.
