ever wonder how you could make the traps with engine blocks and spinning blades like valve did for ravenholm well, now you can

heres a zip file with the vmf and bsp

what i did basically is

made the engine with a prop_static

made a prop_physics_multiplayer for the blade and lined it up to the engine according to the "hole" or gear or w/e

then i used a phys_hinge to hinge the blade to the engine by using the origin circle in the center to set the exact point of hinge for the model

then a phys_motor that spins the blade

for more specific details just look at the vmf and all the tabs in the entity properties, so the blade doesnt go cookoo

bump

sweet. imagine flugplatz (sp?) with planes that featured spinning propellors. imagine the chaos that would ensue.
