The engine can load and render the maps. The Unrealscript VM is almost feature complete - only arrays and network conditional execution are not implemented yet.
It will attempt to load all level actors and initialize the map. However, while the menus and the HUD will appear, there are still many native functions not implemented yet. It is also quite possible some events aren't firing as they should. You will therefore see exceptions shown if you interact with them and that is where the project is at.
At the time of this writing, SurrealEngine can detect the following UE1 games:
- Unreal Tournament (v436, v451b, v469(a, b, c, d, e))
- Unreal (v200, v209, v220, v224v, v225f, v226f)
- Unreal Gold (v226b, v227(i, j, k_11, k_14))
- Deus Ex (v1002f, v1112fm)
- Klingon Honor Guard (219)
- NERF Arena Blast (v300)
- TNN Outdoors Pro Hunter (v200)
- Rune Classic (v1.10)
- Clive Barker's Undying (v420)
- Tactical-Ops: Assault on Terror (v3.4.0 and v3.5.0 - both running under UT436 and UT469 engines)
- Wheel of Time (v333)
Note
From the list above, only Unreal Tournament v436 and Unreal Gold v226 is in a relatively playable state. Running any other game (and UT versions) can and will result in crashes.
- Movers:
- Some buttons are too easy to push, like the ceiling button in Kevlar Suit room in Vortex Rikers. You just need to pass under it while in the original you'd have to bump into it
- Projectiles pass through some movers
- It is possible to get stuck on some movers when approached from certain angles
- Mirrors/reflections rendering is a bit buggy, especially around the edges of world geometry.
- Portals:
- They somewhat work, but might end up "pushing" players/projectiles in unexpected directions.
- No portal rendering yet.
- Semisolid brushes are finicky. Usually you'll fall through them as if they weren't there.
- No dynamic lighting support (Dispersion Pistol projectiles/Flares don't illuminate their surroundings)
- Bot and Scripted Pawn AI isn't fully functional due to the related native functions not being implemented. All they currently do is to sometimes retaliate if attacked, and pick up nearby items.
- Bots literally rotate their entire body (feet off the ground) to look up/down in ways they shouldn't be able to.
- Waving water textures at the end of waterfalls render broken. Easily observable in NyLeve's Falls (Unreal) or DM-ArcaneTemple (UT)
- Underwater collisions are somewhat buggy, especially on Klingon Honor Guard
- Player-to-decoration and player-to-other-pawns collisions aren't properly implemented. The player usually gets stuck and if they manage to get free they end up dying because SE thinks that they've fallen from a great height.
- If the player currently has a power-up active that tints the screen (like Invisibility or Energy Amplifier), the tint remains (and accumulates if a new power-up of the same type is picked up and activated) until the player switches to a different map.
- viewclass command crashes with null deref.
- Sometimes opening a map crashes the engine with a "Failed to spawn the player actor" error.
- Third person weapon meshes do not get rendered.
- Inventory from loaded saves do NOT transfer to the next map.
- Saving packages (.u[xx] files, game saves, etc.) functionality is not fully implemented yet.
- There is no OpenGL renderer.
- There is no networking support at all.
- By design, native mods will never work with SE. Thankfully these kind of mods are extremely rare.
- [Linux/ZWidget] - Wayland backend is somewhat buggy due to Wayland APIs being unpleasant to work with, to name a few things:
- Menus don't properly position themselves.
- Sometimes menus remain persistent (due to rapidly switching?)
- Running any ZWidget app (launcher/SurrealEditor) on GNOME will probably lead to not being able to move the window around, because ZWidget has no custom window decorations (ZWidget uses server side decorations when they're available)
226 version of the game launches. Menu options works most of the time. Single player maps can be played, as well as botmatches. The AI will behave more or less the same as how they behave in UT.
- [227*] Many new native functions/features are not yet implemented.
- Some UPak native functions are not implemented yet.
- Nali Fruit Seeds and ASMDs in a map don't render, but are pickable.
- ASMD tertiary fire rings render wrong.
436 version of the game launches. Menu options will work and botmatches can be played, however the bots will barely have any AI (they move around sometimes and retaliate upon being attacked), and some maps might have some functionality missing.
- [469*] Many new native functions/features are not yet implemented.
- Shock Rifle beams render glitchy.
- Player can slide through on some of the catwalks in the room with lava in DM-Conveyor
1112fm version of the game boots to title screen and the beginning sections of the training map can be played. Nothing much else has been tested, so expect crashes.
- Some native functions are still not implemented.
- Conversation system is not fully implemented yet.
- If you click on the area where the saves should be in the Load Game menu the buttons below stop working so you cannot go back.
- In-game HUD is mostly invisible except for the Incoming Transmission part.
- DataCubes and books cannot be read yet.
- Currently, game crashes immediately due to SE being unable to find "TO_Replacer.ini".
- Attempting to bring up the menus crashes the engine.
- Opening up any map crashes the engine.
1.1 patch of the game launches. AI behaves more or less the same as the other games.
Known bugs list is quite small right now because this game isn't tested as much as Unreal and UT yet.
- Cannot set keybinds in-game (Modifying the ini file works though).
- Trying to start a botmatch crashes SE.
They crash the engine upon startup for various reasons. Will probably take quite a while before the necessary functionality gets implemented.
