- When using both scaling flags, by default, the effect only reaches half peak going either way. This forces it to go all the way to the top (or bottom if using QF_MAX) before scaling back to its original height..
- QF_SCALEUP behaves like QF_SCALEDOWN: it gradually scales the tremors, only going upwards.
- QF_SCALEUP and QF_SCALEDOWN can be combined to make an earthquake that gradually smoothes in and out.
- QF_MAX can be used to invert this behavior, where it starts at the peak of the amplitude, fades out half way, and then grows back to maximum.
- Unlocks the full potential of using quakes, including the Z axis. Each intensity applies to X/Y/Z planes whenever a player is experiencing it.
- Flags:
- QF_RELATIVE - Adjusts the quaking of the camera to go in the direction its aiming (X: forward/backward. Y: Left/right.)
- Plans for including pitch will be implemented in the future for the Z axis with relativity.
I have no idea why this was ever deemed proper - but it clearly breaks some Hexen maps and it not even remotely mimics the original behavior. Even now, it's not the same but since the items fall down they at least end up where they are supposed to be.
- ang_offset: the extra angle to apply to the actor after calculating the maximum turn.
- pitch_offset: Just like ang_offset, with pitch instead.
- FAF_BOTTOM: Aim straight for the actor's z coordinate, not with +32 units.
- FAF_MIDDLE: Aims for the direct middle of the actor.
- FAF_TOP: Aims for the very top of the actor.
- FAF_NODISTFACTOR: Use the raw pitch offset without calculating it into the distance of the aimed actor.
- The error "You cannot pass parameters to..." used the most recent token,
which was always ( and not the function name. (Note that this was
already fixed in the scripting branch, so this is probably going to be a
conflict. Meh.)
- Added A_Warp flags:
- WARPF_BOB: Gets the bob offset of actor pointer with the FLOATBOB flag.
- WARPF_MOVEPTR: The function is inversed to move the pointed actor with applied flags, but only the original caller will make the success/jump.
- Rippers will rip through anything with an equivalent ripper level, or if their level is between or on the min and max ranges.
- If no min or max is defined, it simply checks if the monster's ripper level is lower than the missiles.
- Functions: A_SetRipperLevel(int level), A_SetRipMin(int min), A_SetRipMax(int max)
- Properties: RipperLevel, RipLevelMin, and RipLevelMax.
- RipperLevel: Applicable to monsters and projectiles.
- RipLevelMin and RipLevelMax are only useful on monsters.
- By default, all are 0.
- Do a filter and species check first to save time.
- Added DMSS/KILS/RMVF_EITHER, which means if the actor is of type or species, it counts.
- A_DamageTarget(20,"Normal",DMSS_EITHER,"DoomImp","CyberdemonSpecies")
- This affects actor DoomImp, and anything that's of species CyberdemonSpecies.
- Added a little more documentation via comments.
- Added two more flags for each of the functions, EXFILTER and EXSPECIES.
- Stands for "exclude filter/species" and makes the function not take them into account.
- Cleaned up the code and placed all the checking in their own subfunctions.
- The wiki said the minimum distance to teleport defaults to 0, actor.txt on the other hand said otherwise. I was wondering why it was still broken somewhat...
- Prevent stickiness from happening, a.k.a. getting stuck in ceiling or floor and letting the engine unstick the actor. This caused velocity loss.
- TF_KEEPVELOCITY: Keep the velocity after teleporting.
- TF_KEEPANGLE: Don't use the special spot's angle.
- TF_USESPOTZ: Normally, this function
- TF_NOSRCFOG: Don't leave fog at the previous location.
- TF_NODESTFOG: Don't leave fog at the arriving location.
- TF_USEACTORFOG: Use the actor's TeleFogSourceType and TeleFogDestType properties.
- TF_NOJUMP: Don't require or cause a jump. In this case, put 0 (or "") in for the jump destination when using CustomInventory items to teleport actors around.
- New properties include TeleFogSourceType and TeleFogDestType.
- TeleFogSourceType is the fog left behind where the actor teleported away from.
- TeleFogDestType is the fog the actor sees when it arrives at its destination.
- Added A_SetTeleFog(<oldpos>,<newpos>) -- oldpos sets TeleFogSourceType, newpos sets TeleFogDestType.
- CLOFF_SETTARGET | CLOFF_SETMASTER | CLOFF_SETTRACER
- An actor that causes A_CheckLOF (and only an actor) to succeed will set the intercepting actor as its target, master, and/or tracer, respectively.
- FTF_REMOVE: Removes the actor when the alpha hits a certain level.
- - A_FadeIn - 1.0
- - A_FadeOut - 0.0
- - A_FadeTo - Alpha target level reached
- FTF_CLAMP: Automatically fixes the alpha so it won't leave the range [0.0, 1.0].
- Added: A_TakeFromChildren
- Added: A_GiveToSiblings
- Added: A_TakeFromSiblings
- Added the following flags for A_RadiusGive:
- RGF_NOSIGHT: Exclude sight check from distance.
- RGF_MISSILES: Missiles can take inventory items.
Added cl_predict_lerpscale and cl_predict_lerpthreshold
Added options in menudef
Made sure that lerping cannot extrapolate or run on small scales
Lerping gets reset when rendering interpolation does or respawn
- fixed: The shader code for handling special fixed colormaps did not use the color vertex attribute which was most evident with the 'shadow' render style on the spectre.
- RMVF_MISSILES removes missiles.
- RMVF_NOMONSTERS ignores monsters.
- RMVF_MISC includes non-monsters and missiles.
- RMVF_EVERYTHING disregards all checks and remove it.
These flags now apply to the following in addition to the new function:
-A_RemoveTarget
-A_RemoveMaster
-A_RemoveTracer
-A_RemoveChildren
-A_RemoveSiblings
- Added A_KillTarget(damagetype, int flags).
- Added A_KillTracer(damagetype, int flags).
- Added A_RemoveTarget.
- Added A_RemoveTracer.
A_Kill (Master/Target/Tracer/Children/Siblings):
- KILS_FOILINVUL: foils invulnerability.
- KILS_KILLMISSILES: destroys projectiles. Does not work on invulnerable
projectiles without KILS_FOILINVUL, and doesn't work at all on missiles
with NODAMAGE flag.
- KILS_NOMONSTERS: actors that are monsters will not be killed.
A_Damage (Self/Target/Master/Tracer/Children/Siblings):
- DMSS_FOILINVUL: foils invulnerability.
- DMSS_AFFECTARMOR: damages the actor's armor instead of bypassing it
entirely.
- DMSS_KILL: damages the actor by its remaining health (useful for
modular DECORATE programming).
- Added A_SpawnItemEx flags:
- SXF_SETTARGET: sets the calling actor as the target.
- SXF_SETTRACER: sets the calling actor as the tracer.
Both of these functions take priority similar to SXF_SETMASTER over
SXF_TRANSFERPOINTERS.
- Added delay times of all players to the scoreboard
- Removed balancing from packet-server (tried it, didn't work)
- Calculations remove an extra tic to account for possible bias
- Guests can now attempt to match latency with the arbitrator.
(net_loadbalance)
- Added althud feature to show arbitrator and local latency.
(hud_showlag 1 is on for netgames, 2 is always on)
- avoid rebinding the same texture multiple times, as there's considerable overhead in the texture manager.
- check gl_sort_textures only once per scene, not per draw list.
Sadly, anything else makes no sense.
All the recently made changes live or die, depending on this extension's presence.
Without it, there are major performance issues with the buffer uploads. All of the traditional buffer upload methods are without exception horrendously slow, especially in the context of a Doom engine where frequent small updates are required.
It could be solved with a complete restructuring of the engine, of course, but that's hardly worth the effort, considering it's only for legacy hardware whose market share will inevitably shrink considerably over the next years.
And even then, under the best circumstances I'd still get the same performance as the old immediate mode renderer in GZDoom 1.x and still couldn't implement the additions I'd like to make.
So, since I need to keep GZDoom 1.x around anyway for older GL 2.x hardware, it may as well serve for 3.x hardware, too. It's certainly less work than constantly trying to find workarounds for the older hardware's limitations that cost more time than working on future-proofing the engine.
This new, trimmed down 4.x renderer runs on a core profile configuration and uses persistently mapped buffers for nearly everything that is getting transferred to the GPU. (The global uniforms are still being used as such but they'll be phased out after the first beta release.
- we need to check all GL versions when trying to get a context because some drivers only give us the version we request, leaving out newer features that are not exposed via extension.
- added some status info about uniform blocks.
- reactivate alpha testing per fixed function pipeline
- use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.
Due to the way the engine works it needs to render a lot of small primitives with frequent state changes.
But due to the performance of buffer uploads it is impossible to upload each primitive's vertices to a buffer separately because buffer uploads nearly always stall the GPU.
On the other hand, in order to reduce the amount of buffer uploads all the necessary state changes would have to be saved in an array until they can finally be used. This method also imposed an unacceptable overhead.
Fortunately, uploading uniform arrays is very fast and doesn't cause GPU stalls, so now the engine puts the vertex data per primitive into a uniform array and uses a static vertex buffer to index the array in the vertex shader.
This method offers the same performance as immediate mode but only uses core profile features.
- Added a segment of code that now makes the intermission wait for all
players before advancing, instead of continuing on any player. A "ready
icon" shows to reflect this.
- The Deathmatch intermisson couldn't show the ready icon (because it
just used the ingame scoreboard), so a proper intermission was added,
which reflects the same design as the coop scoreboard.
- The colour column wasted more space then it should have needed, so it
was replaced with player colour backgrounds.
- Slight y offset adjustments to make everything fit in 320x200
properly.
- Also fixed some very strange thing in the shader's desaturate function. For unknown reasons using the 'mix' function there did not work.
- fixed: The fog boundary special shader could not be used.
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...
This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.
- remove thing color from lighting calculations.
- implement alpha textures and inverse sprites for infrared as texture modes. This still requires some handling for the alpha texture mode for non-shader rendering because there is no way in the fixed pipeline to do it. The inverted texture effect can be done with a texture combiner.
- fixed: ThingColor for sprites was set in the wrong place. It must be in the Process function, not in the lighting calculation.
- added functions for isolated calculation of sprites' dynlight color.
Namely, acolyte, shadow acolyte, reaver, stalker, and turret. Info on
which states needed the slow flag was obtained with Quasar's permission
by looking at G_InitNew() in g_game.c and the info.c state tables from
Chocolate Strife.
Also added fast flag to acolyte states that needed it, based on the same
source.
- For maps like xtheateriii that expect non-blocking push lines to
activate when you are standing on them and run into a completely different
line, there is now this compatiblity.txt-only flag.
- Added freedoom2.wad as valid alias name (freedoom1.wad already
existed).
- Renamed titles to Freedoom: Phase 1 and Freedoom: Phase 2.
- Reordered to put Phase 1 above Phase 2 in the IWAD picker.
