Prop physics

Template:Base point It is used to add rigid, VPhysics-simulated models to the world.

The only value required for prop_physics to work is a path to a model. As long as that model is physics-enabled, the correct data will be loaded from it when the map starts. It is possible to change any embedded physics data with the "Override Parameters" keyvalue.

Tip:Multiplayer maps should use prop_physics_multiplayer or prop_physics_respawnable. To create a jointed physics object, use prop_ragdoll.

Note:prop_physics can be parented if the 'parentname' value is manually added with smartedit turned off. Parenting prop_physics can be unpleasant and buggy in some situations.

Consistency

Todo: Move this section to its own article.

Consistency becomes a large problem when dealing with the many prop models that the Source engine provides. From a player's perspective, object interactivity should remain consistent across all the levels of your game / mod. (Why? Shouldn't the level designer has control over this, dependent on the context of the prop's use?) To enforce this, the game-related data of props is stored within the model itself.

Models that are meant to be physically simulated (chairs, tables, wooden planks, etc) will remove themselves if they are placed as prop_static or prop_dynamic entities. Other game-related data, such as mass, "health", gib amount & models, and so on are all stored inside the prop model as well.

The method by which they are stored, and guidelines for how to set it up, can be found in the Prop Data section of the model's QC file.

RenderFields:

Alpha <integer 0–255>
