Additional showcase videos can be found in the playlist here.

1. Have Ninja installed.
2. Drop MaxXPHelper.vdf file into <gothic-main-dir>/Data

Should work with G3D11 renderer and Union plugins (at least those that just add some quality of life features). Known issues

New Balance - didn't test and not going to.

Shows a text alert if XP is lost when NPC dies (showcase video), following the below rules:

• NPC got killed by non-party-member NPC and XP haven't been received before (or considerG1DoubleXPGlitch=1 in which case player must finish everyone off with a bow or magic);
• NPC got killed by game scripts (B_KillNpc/B_RemoveNpc) and player could have beaten them but hadn't, which is:

  • NPC wasn't immortal just before getting killed/removed;

  • NPC death wasn't scripted in a way that player couldn't have done anything about it. For example:

    • Carristo's death in Gothic 1 CH4 is ignored, however death of other fire magicians won't be (showcase video);
    • Stone guardians next to the Jharkendar portal in G2 NotR which get killed by a script run on the first visit are ignored, however, deaths of any remaining guardians after Raven is defeated won't be;

    A lot of G2 NotR deaths cannot be detected in any other way than by having a list of such NPCs. In case the one shipped by default is incorrect or non-exhaustive, it can be easily overriden.

    Plugin expects the blacklist to be provided in a file located at a path from deadOnArrivalNPCListPath config option (default system\maxxphelper_deadOnArrivalNPCList.txt). This should be just a single line of semicolon separated list of NPC instance names (i.e. what you type in insert vob <code> console command to spawn an npc). The file should end with a semicolon folowed by a newline (because of "reasons").

  • [considerG1DoubleXPGlitch=1 only] Player or party member killed NPC with melee finisher (showcase video);

  • [considerG1DoubleXPGlitch=1 only] Player or party member killed NPC without beating them up first;

  • [considerLevelZeroNPC=0] Level 0 NPCs are ignored (they give no XP with vanilla game's formula - npc_level * 10);

In addition, a failure tracker can be displayed at the position of the NPC which triggered the alert (showTrackerOnDeathAlert=1).

Usage: press a key configured by toggleXPNPCLocatorKey ini option (by default V) to toggle rendering on and off.

Draws trackers at position of NPCs which hero can still beat up to gain more XP (showcase video).

• Filters out NPCs with immortality flag set;
• Takes considerG1DoubleXPGlitch into account (if NPC was beaten before, tracker will display an icon suggesting a ranged kill);
• Takes considerLevelZeroNPC into account;

You can read the source of XP_NPC_LOCATOR.D to understand this in detail.

In short: nearby NPCs (whose AI is processed by game) are always updated & rendered on every frame.

Inactive NPCs (whose AI is frozen) are incrementally processed (couple NPCs every frame)so it doesn't impact framerate too much. NPCs are divided into "buckets" based on their distance to the Hero. Only first few buckets (representing NPCs closest to the player) are rendered, other buckets are skipped.

It would be possible to render all NPCs but this would likely lower framerate too much and cause significant visual clutter. The primary purpose of this feature is to show player if they forgot about a monster or two while clearing an area and, if so, point to the nearest one. Rendering everything, especially at the start of the game, makes very little sense.

Enabled with considerPickpocketing=1 ini option. Videos showcasing the feature are here, here and here.

This integrates with XPNPCLocator to display a pickpocket tracker if NPC hasn't been pickpocketed yet (and is possible to). Color of the tracker depends on whether dexterity requirements are met or not. For some edge cases, it's not possible to tell (at least using the approach I chose) so there're 3 colors in total - pickpocketSeemsEnoughDexColor, pickpocketSeemsNotEnoughDexColor and pickpocketIndeterminableColor. Most of the time, indeterminable color is applied only if hero's dexterity is very low, under 20ish (so irrelevant in practice).

You can also opt in for XPNPCLocator to show only pickpocket trackers with showPickpocketTrackersOnly=1 ini option (by default it's off).

In addition, pickpocketable NPCs are continuously scanned and a text alert (similar to DeathAlerts) will pop up when NPC can no longer be pickpocketed which could happen if:

• NPC died
• pickpocket dialogue choice become permanently unavailable. This should work in cases like the item is looted, for example Lehmar.

Some NPCs are never pickpocketable (no way to start a dialogue, like Skinner, or bugged, like Edda). To ignore those NPCs use pickpocketBlacklist ini option. By default it's set to:

VLK_491_Vanja;VLK_471_Edda;BDT_1082_Addon_Skinner;VLK_436_Sonja;VLK_4201_Wirt;

which should be accurate for a mercenary/dragon hunter playthrough.

You can read this if you want more details how this insanity works under the hood.

After installing, start a new game or load a save to get the defaults auto-set in system/Gothic.ini file. The section is called [MaxXPHelper-V1]. No UI available, sorry, I can't be bothered. Most defaults should be good enough so no need to go through all of the below.

Following is the default for Gothic 2 NotR. I extracted this by running a script located at tools/g2notr_print_doa_npcs.py against the scripts from here. For Gothic 1 its empty as there're no cases where a seemingly normal NPC gets killed off-screen by game's scripts pretty much the first time player arrives in new location. Note: this must be terminated by a semicolon and end with a new line.

1. Get GothicVDFS tool (if you have Steam version of Gothic 2 then GothicVDFS 2.5 can be found at <steam gothic 2 install dir>\_work\tools\VDFS)
2. Run .\build.bat once to get dot.env file created in the repo root and set:
   • GOTHIC_VDFS_PATH var to GothicVDFS.exe path
   • [Optional] set SEMICOLON_SEPARATED_EXTRA_OUTPUT_PATHS to your Gothic/Gothic 2 Data folder

Assuming GOTHIC_VDFS_PATH is set and your working directory is the repo root - run .\build.bat. MaxXPHelper.vdf will be at .\build\ and paths set in SEMICOLON_SEPARATED_EXTRA_OUTPUT_PATHS variable

Framerate will suffer with the locator enabled, especially if max rendering level (toggled by pressing key set at toggleTrackersMaxRenderingLevelKey) is on or in crowded areas such as Khorinis. At the current state, optimizing the performance further would require significant effort which is probabably not worth it. The use case for this feature is not to run around the map with locator being constantly on. It's only supposed to help track down any missing monsters/pickpocket opportunities.

Potential improvements which come to my mind are:

• transform vertices on GPU (vertex shader?) instead of CPU for more parallelism, faster floating point arithmetics and shorter time when main game's thread is blocked; Note: I'm no 3D Graphics expert but I believe game uses an old DirectX 7 renderer so doing the above in a way that leaves the plugin compatible with both vanilla game and custom renderers (GD3D11) might be tough;
• batch the draw calls to DirectX device (draw primitive indexed or similar, not sure if it's even available with DX7);
• use a BSP Tree and do the frustum culling properly so not all trackers are iterated each frame (which is slow if there's a lot of them active); alternatively - turn trackers into actual VOBs and have game engine do it...
• Process NPCs on a separate thread; This would require a rewrite to Union and C++ as calling Daedelus scripts from separate thread is not a feasible solution; Also I doubt this particular enhancement will make a dramatic difference;

I believe none of the above are low hanging fruits and I have no time to explore the above so sorry, it'll run like crap :(.
