The weapon_crossbow entity can be used to place a crossbow in a map. This crossbow can be picked up and used as a weapon. When picked up, the player is given 5 bolts and the crossbow if they do not already possess one. Additional bolts (up to 11 in total) can be picked up. A roll of crossbow bolts can be placed in a map with the item_ammo_crossbow entity. The crossbow also follows all physics rules as if it were a prop_physics. It is relevant in Half-Life 2 single and multi player.
Name: allows you to name the entity. Useful if it is parented to something else or needs to be uniquely identified. Otherwise, leave this blank.
Pitch Yaw Roll (Y Z X): The orientation of the model. These can be manipulated manually by placing a number from 0 to 360 for each value or by rotating the model in the 2D views. All values are in degrees.
Start Constrained: Prevents the model from moving. Off by default.
