Creating Ragdoll Models
Difficulty: Advanced |
| Category: CS:S > Modeling | Author(s): |
The following tutorial shows how to create a ragdoll model. These models are for more than just characters. The famous mattress model is a ragdoll model. If you want parts of a model to swing or move separately from the rest then you should use a ragdoll model. To use a ragdoll model you use prop_ragdoll instead of prop_static or prop_dynamic.
To create a ragdoll model you must create one with separate bones for each part of the model which will move. Here is an example of a simple ragdoll model in milkshape.
Ragdoll.gif
Create a reference smd file from milkshape or your favorite editing tool.
If you were going to just compile this model as a static prop you would use the following .qc file
$modelname "mymodels/myragdoll.mdl"
$scale 1.0
$cd ""
$body "Body" myragdoll.smd
$cdmaterials "models\mymodelmaterials"
$staticprop
// 1 sequence
$sequence idle "myragdoll" fps 5 ACT_IDLE 1
$surfaceprop "wood"
$keyvalues { "prop_data" {"base" "wooden.large" }
$cdmaterials "models\mymodels"
$collisionmodel "myragdoll.smd" {
// Mass in kilograms
$concave
$mass 500.0
}
To change this to a ragdoll model you change the $collisionmodel to $collisionjoints and specify how the joints can rotate with respect to the root joint. An example .qc is as follows
$modelname "mymodels/myragdoll.mdl"
$scale 1.0
$cd ""
$body "Body" myragdoll.smd
$cdmaterials "models\mymodelmaterials"
//$staticprop
// 1 sequence
$sequence idle "myragdoll" fps 5 ACT_IDLE 1
$surfaceprop "wood"
$keyvalues { "prop_data" {"base" "wooden.large" }
$cdmaterials "models\mymodels"
$collisionjoints "myragdoll_ragdoll.smd" {
// Mass in kilograms
$rootbone "joint1"
$concave
$mass 80.0
$inertia 5.00
$damping 0.01
$rotdamping 1.50
$jointconstrain joint1 x limit 0.000000 0.000000 0.000000
$jointconstrain joint1 y limit 0.000000 0.000000 0.000000
$jointconstrain joint1 z limit 0.000000 0.000000 0.000000
$jointconstrain joint2 x limit -90.000000 90.000000 1.000000
$jointconstrain joint2 y limit -90.000000 90.000000 1.000000
$jointconstrain joint2 z limit -45.000000 45.000000 1.000000
$jointconstrain joint3 x limit -90.000000 90.000000 1.000000
$jointconstrain joint3 y limit -90.000000 90.000000 1.000000
$jointconstrain joint3 z limit -45.000000 45.000000 1.000000
}
Each of the jointconstrain commands control the joint rotation in a specific axis. For example the above .qc allows joint2 and joint3 to rotate +/- 90 degrees in the x and y and +/- 45 degrees in the z (up/down) axis.
In the above example I used boxes for each of the joints, so I don't need to create a separate ragdoll collision model. If your model is more complicated, then for the collision model you should create a new .smd with one box assigned to each joint. The box will be used for collisions for that joint and the size will determine the weight of the joint.
