L4D Mapping: Prop Overview- Video Tutorial

Props Overview:

Prop_Static: physical model that acts as a solid object. It cannot move, animate, or accept input. Prop_Static doesn't actually exist as an entity after the map has been compiled. The vast majority of models in Valve's maps are set to prop_static.

Prop_Physics: used to add rigid, v-physics simulated models. Cannot be parented.

For multiplayer maps use prop_physics_multiplayer or prop_physics_respawnable.

Prop_Dynamic: used to add a moving or animated model to a map. Prop_Dynamics are able to be parented to the other entities, thus making them moveable and animatable.

Prop_Ragdoll: simulates physical joints inside a model. The model must have joints already in-place for prop_ragdoll to work.

Creating a Rotating Fan:

Use a prop_dynamic for the fan blades.

Insert an entity prop_dynamic and choose fan blades.

Create a brush with invisible texture applied. Place it under the fan.

Tie the brush to an entity func_rotating by selecting the brush and press Ctrl+T

Select func_rotating

Name func_rotating with fanblade. Name could be anything you want.

Select the fan blades.

Go to object properties and under parent, input the name of the func_rotating entity.

Func_Rotating flags tab, set to Start On.

Set the speed and any other properites under func_rotating that you want.

Please help AlexG 25 Aug 2009, 21:03 Thanks Maleitch, About prop_dynamic and fun_rotating. Yes, the positioning acts as the center axis where it rotates from. As long as it is in the center of the object's rotational axis. Doesn't matter if its above or below. Maleitch 25 Aug 2009, 20:40 First of all, I love the site and check it daily so please know that your work is greatly appreciated. Concerning your prop_dynamic fan blades. Does the alignment of you func_rotating entity really matter for the prop to rotate? Does it have to be centered and just underneath? Finally would love to see a tutorial using some advanced use of props and different functions such as train_path to create scripted sequences. Yeah I know this is a biggie. Thanks again for all your great work. ClayJitsu 24 Aug 2009, 14:55 Another. Great. Tutorial. Powered by Scriptsmill Comments Script
