Hello,
i try to “develop” my first Traitor Item for TTT. First of all i have to say that most parts of the Code i copied from persistens codes. It is not my purpose to steal codes from another developers here, but i use it to learn about the programming language and will use this for my own test purpose, not to publish it on any platform (e.g. steam workshop or anyother). If this breaks the rules, feel free to delete the Thread/Post.
I try to develop a Snark Spawner as Traitor Item, which will attacks the Innocents. If you dont know what Snarks are, check the Half-Life 1 Enemylist via Google to check that.
When i start my Server with my Addon i get this error:
[ERROR] lua/entities/npc_vj_bmsno_snark/shared.lua:3: attempt to index global ‘SWEP’ (a nil value)
