Creating Weapons
Never mind i figured it out
https://developer.valvesoftware.com/wik ... ng_Weapons
Hey Fellows,
Sorry to bother you again. I really like changing the weapon_portalgun.txt file to change my weapon, however i was wondering if there is a way to dynamically change this in mid-game. I want to have about 5 different weapons in the level so if anyone knows how to get this done i would be grateful.
I don't mind scripting so if you know a way to do it that way its okay.
I don't think it's possible to actually change weapons in Portal 2 (Valve removed a lot of code for features they weren't using). You might be able to fake it by parenting a weapon model to the player, or using a logic_measure_movement (can't remember which works better). Perhaps you can set the weapon_portalgun model to be an invisible model, and parent to the same attachment it uses. Then you can make logic to enable/disable draw of custom weapons, probably using an animation first to make them drop down offscreen like the portalgun has.

This is what i have already done in the past, and i do agree it is a sure way to do it. I would just be alot smoother and cooler (i think) if i could add actual weapons instead of parenting models.
Please if anyone has anyother ideas don't be afraid to post 
Unfortunately there's no real way. Trying to mess with the viewmodel entity via scripting generally leads to either no effect or crashes.
To get a very smooth moving effect on custom viewmodels, you can technically parent models to the portalgun viewmodel, turned invisible, but it is incredibly unreliable and generally not a good method for weapons, as it requires tons of console commands and perfect positioning. I don't recommend it. However, if you are making a sourcemod, then you can edit the portalgun model and change the potatOS bodygroup to look completely different, such as a paint gun, and then swap between those using a logic_playerproxy.
