Picks

[macklebee]

Is there a way to relate a camerapick entity to a entity that is found by looping thru the worlds entities? when I do a getkey("name") for example for both, the camerapick returns U3D_MESH and the looped entity returns the user defined name of the model..

 

Also, if I do an entitypick, since the radius parameter doesn't work, how do i know what direction the raytrace is occurring?

The entity returned by the CameraPick is the actual mesh itself. You have to call GetMeshModel(pick.entity) to get the TModel that actually has the proper keys for it.

 

Since picks occur only to meshes, and not models or physics, you have to get the Model parent of the picked mesh in order to utilize the key system, message system, etc. on a picked entity.

ah! makes sense... thanks!

EDIT---nevermind... it works. strange there is no mention of it in the wiki...

this doesn't exist for BMAX? so this is a lua only command? or is there a bmax version of this with a different name?

GetMeshModel() is not an engine command. It just goes through parents until a model entity is found.

[macklebee]

so how would you do this in bmax? GetParent(mesh)?

[macklebee]

ah... its ugly but it works

name = GetEntityKey((GetParent(pick.entity)), "name")

[TylerH]

GetMeshModel does a repeat until parent==nil loop to continuously get the parent until you get the highest level parent of the picked entity.

 

It would be nice to have an engine command like GetMeshModel, or something generic and widely usable like GetRootParent.
