// Create the weapon entity
new iEntWeapon = create_entity( "info_target" );

// Set the entity's class
entity_set_string( iEntWeapon, EV_SZ_classname, "weaponbox" );

// Set it to follow (so it will follow its owner)
entity_set_int( iEntWeapon, EV_INT_movetype, MOVETYPE_FOLLOW );

// Make the weapon solid
entity_set_int( iEntWeapon, EV_INT_solid, SOLID_NOT );

// Set the owner of the weapon to be the entity you want to have the weapon
entity_set_edict( iEntWeapon, EV_ENT_aiment, iEntOwner );

// Assign the weapon entity a model
entity_set_model( iEntWeapon, "models/p_m4a1.mdl" );

I put a list of the models in this array so you guys can use this to give it a random weapon or something (BUT YOU MUST change the model's sequence to match the weapon).

new szWeaponModels[31][32] =

I'm posting this because I was trying to figure this out for a long time, then I found a resource on google that talked about MOVETYPE_FOLLOW and it explained the above. So enjoy

GJ Pimp Daddy. Would the same thing work with DoD? Using a DoD gun model I mean.

Added into helpful / useful stuff

So this means that the gun appears in the right spot in the player's hands. But what you said about model animation, what do you mean?

[GamerXR72]

Could this be used to let someone buy the rocket launcher from single player half-life, from a custom menu like the warcraft 3 shopmenu, or is this just replacing the weapon model the player sees?

[Geesu]

you have to make sure the model's sequence is correct. I think I used 4 to hold the m4a1 and ak, etc... mp5...

Only some weapons look correct, you'll have to play with it.

And yes it works for dod...

And no this doesn't allow to add a rocket launcher.

[LynX]

Actually, if you change your model, and make plugin fires rocket when that model is enabled, sure, why not?

[Geesu]

Well yea you could make someone hold a rocket launcher. What I'm saying is that the code provided above won't have the functionality to shoot it. You'd just be "holding" a non-functioning rocket launcher.

[[DoD]GoldenEagle]

Do you have to make a new...

 

entity_set_model( iEntWeapon, "models/p_m4a1.mdl" );

Such as...

// Assign the weapon entity a model
entity_set_model( iEntWeapon, "models/p_mp5.mdl" );

[Major_victory]

how would you go about making the animations work? this is something i've always had problems with...
