Portal Gun - Reworking in LUA code (Aperture Science Handheld Portal Device)

This is a reworked version of the addon "Portal Gun - Aperture Science Handheld Portal Device" by prynncesslua / Bobblehead.

After numerous re-uploads to fix the old version, I decided to start from scratch by reworking the original addon. It took me days to implement everything and repeatedly test the Portal 1 campaign to fix certain bugs. In the future, I will release regular updates, but if you encounter any bugs or Lua errors, please:

STOP RE-UPLOADING ADDONS TO MAKE A FIXED VERSION OF THEM TO YOUR LINKING.

I would like the This new version will NEVER be re-uploaded or reused for any future add-on projects. Please respect the work of others, and I will have to accept the consequences. Thank you for your understanding.

Description:

The exemplary add-on for the system manager (add-on is hidden because the update is not yet ready): Portal Guns from Portal: Revolution [GMod Port]

• Portal Gun works exactly like in the base game, with new features included and some never before seen in certain versions. You can now play the Portal 1 Campaign without any problems!

• The settings can be found in the Spawn Menu: "Options > Portal Gun" as well as a new Stool for portalable or non-portable surfaces, not forgetting a Stool for cloning and laser effects through portals!

• Compatible with "VRMod x64 - Extended" with new portal rendering and movement specifically for VRMod!

• Portals with different colors depending on the index used, from 1 to 5, with the new Render Texture for portals (complete the RT __rt_supertexture1/2).

• Entity surfaces starting with func_* are now portalable!

• Pickup with Portal Gun has been reworked.

• Choose different borders between the "Retail / Swirl / Vines / 2005" versions.

• Portal shots in the pedestal are finally fixed with the new projectile configuration.

• New entities and reworked versions.

• Collapses for portals no longer fizzle, and the ERROR model no longer appears!

• You can also view portals through walls, just like in Portal 2!

• Entities such as grenades, missiles, and NPCs pass through the portals!

It is now compatible with Portal 2 SWEPs - The Aperture

Addon Issues Listed:

• Portal projectiles do not exist in multiplayer. (THIS IS FIXED!!!)

• Props sometimes fall through the ground when moving through the portal. (This bug is very rare if the object is a little far from the portal's collision point when on the ground or against a wall.)

• Skybox sometimes doesn't draw in the portal. (THIS IS FIXED!!!)

• The model is barely visible through walls, including the ground. (This is rare.)

• Portals behind each other cause bugs. (This depends on the line of sight, maps, and player model. There's a command that allows you to disable your player model in the Render Texture settings for portals in first-person view.) (but only on PC)

• The views between portals are not synchronized with other portals in Multiplayer and Single Player. (THIS IS FIXED!!!)

• Portal NPCs do not look at you in the portals.

• When you are crouching in front of a ground portal, your field of vision will start to wobble or eventually become blocked (THIS IS FIXED!!!)

• Portal NPCs do not look at you in the portals. (In a future update it's planned, except for the rocket launcher)

• When an object collides with the new side of the portal, the game tends to crash. (THIS IS FIXED!!!)

• The retail portal, it all depends on the index, is rarely black. (because of the ToneMap)

• You cannot change your Viewmodel in Multiplayer (which I can't get to work) (THIS IS FIXED!!!)

• The lack of FPS (unless you have a good PC)

• The "prop_portal" entity simply won't appear in multiplayer if you have too many entities registered on the server. (This only works in single-player, but if you want your portal to be visible, disable one of the addons that has TOO MANY entities registered.)

• The "trigger_portal_cleanser" entity in Lua is no longer replaceable. (Thanks to the September 2026 update of Garry's Mod)
