This is the old Portal 1 source code ported to Source Engine 2013. I made this because I wanted to make proper Half-Life 2 with Portal gun, but I have no idea how to fix all of the bugs that occur in Portal on Half-Life 2 maps (some crashes, displacement collision not working near portals). So I hope someone more experienced with Source engine will help me fix them.
- New "Mod Options" menu
- You can erase portals by reloading portal gun
- Health regeneration is toggleable with "sv_regeneration_enable" or in "Mod Options" menu without annoying red tint
- You can toggle between Half-Life 2 gamerules and Portal gamerules with "sv_use_portal_gamerules". As far as I know it controls if you receive fall damage or not, but it might also control something else, I'm not really sure
- Fall damage is toggleable with "sv_receive_fall_damage" or in "Mod Options" menu (only for Half-Life 2 gamerules, Portal's gamerules always have fall damage disabled
- Flashlight is enabled
- NPCs can actually shoot you now (And even through portals! Because apparently Valve left some code for that. Only at specific angles though)
- Backported crosshair from current version of Half-Life 2
- No crashes on the map load in Half-Life 2 and Episodes
- Even if "sv_regeneration_wait_time" is higher than 1 second, red tint will now be on the screen only for 1 second
- You won't get stuck in non-solid static props near portals
- You can change the maximum delay between shooting a Portal and it opening with sv_portal_projectile_delay (default is 0.5 seconds), if set to a very high number behavior will be the same as in normal Portal
- You can rapid click to shoot Portals faster, like in Portal 2
- You can set either Chell playermodel or default Half-Life 2 playermodel with "cl_playermodel "models/player/chell.mdl"" or "cl_playermodel "none"" respectively or in "Mod Options" menu (you will need to start a new game or load a map through console to see the change though)
- There is HUD QuickInfo (aka crosshair) from Portal's beta. Toggleable with "beta_quickinfo 1|0" or in "Mod Options" menu (the code for it was taken from here and improved upon https://github.com/reepblue/project-beta/blob/master/src/game/client/project-beta/hud_quickinfo.cpp)
- Crowbar swings through Portals
- No crash when Magnusson Device hits the ground
- "impulse 102" gives portal gun
- There's portal gun bind in the settings
- There's no collision for displacements near portals. Which means you will fall through displacements close to portals. Displacements are usually used to make bumpy ground or hills, valleys, trenches, slopes etc. though they also can be flat and just used to blend two or more textures together. It's a pretty complicated issue to fix, so for now get your noclip ready. You can also just avoid displacements near portals by jumping over them for example because it's usually pretty easy to distinguish displacements from normal brush terrain since the brushes are always flat
- There are some visual glitches with portal gun, some of them can be fixed by saving and loading
- Sometimes the game will crash if you place your portals in certain places (like on the floor of the red barn in d1_canals_06) or if you push physics engine too far
- Guns are still attached to NPC's hands when they're supposed to be hidden
- Then you grab something with gravity gun and go through portal weird glitches can happen
- Emplacement gun in d1_canals_01a is a bit broken - you can activate it only at very specific angles
- Particle (and some other colors) are inverted on Linux
- Music can be duplicated sometimes. Use snd_cull_duplicates 1 to fix it, just be sure to set it back to 0 when music ends because other sounds might sound weird if you always have it set to 1.
- GCC 4.8
- Steam Client Runtime
Compiling process is the same as for Source SDK 2013. Instructions for building Source SDK 2013 can be found here: https://developer.valvesoftware.com/wiki/Source_SDK_2013
You will need Portal installed though
Same as Source SDK 2013 mod: https://developer.valvesoftware.com/wiki/Setup_mod_on_steam

If you want the game to behave exactly like normal Portal first use Half-Life 2 binaries not Episodic ones, second, create autoexec.cfg in your mod directory and add those commands:
sv_regeneration_enable 1
sv_use_portal_gamerules 1
cl_playermodel "models/player/chell.mdl"
And it should be just like normal Portal
