Chdata, have you validated that slot 5 actually contains the grappling hook?

That'd cause a problem for Engineer since his tf_weapon_builder (item index 28) is present in that slot. If an Engineer doesn't have a tf_weapon_builder, the `build` command, Contruction kit, and Destruction kit all stop working.

(Side note: Sapper is a subclass of tf_weapon_builder, but for Spy)

Maybe I meant to type 6? idk

This guy titled his thread solved.... but did he even test anything?

I vaguely remember testing it for scout/soldier...

Probably, since you can't equip tf_weapon_builder as engineer in the first place, both items are put into the same slot and it happens to work out, as TF2 does say it's slot 6. (Since primary == 0, slot6 == 5)

Which means multiple weapons would have to be searched in engineer's case, I guess.

Yes I test it and it's working. if it's not work, I can't add SOLVED tag :/
