Prop Physics Flags Explained

Half Life 2 Mapping Tutorial: Prop Flags Explained

Here I will explain some of the flags used for HL2 props (prop_multiplayer, prop_physics etc).  These flags are useful to know about in certain situation, but they arent immediately obvious what they do from their names.You will find the flags in the properties window of your entity, just select the prop and press alt + enter in hammer.



Above you can see the prop flags, and immediately some flags are not well explained. Below I will suggest some uses for these flags:

Start Asleep 

The prop will not move from its position when spawned, which is good for radiators and other objects which should be positioned fixed to walls.  Any interaction including standing on the object and shooting it will cause it to drop to the ground.Therefore, it is advisable to use this flag in cojunction with Motion Disabled and Enable Motion on Physcannon Grab.

Don't Take Physics Damage 

The prop if breakable will not take damage if hit by another prop.  It will still take damage if hit by gunfire or shot against a wall.

Debris 

No information at this time.

Motion Disabled 

Similar to Start Asleep , but the prop will not move even when interacted with.Use in conjunction with Enable Motion on Physcannon Grab to allow interaction after grabbing with the gravity gun.

Enable Motion on Physcannon Grab 

If Motion Disabled is set, the prop will not move until it is grabbed with the gravity gun.
