Nightly

This is a build that is generated automatically from the latest sources every night. It may contain incomplete work-in-progress features or bugs that are not present in official releases.

If you need to report an issue found while using a nightly build, please:

1. Ensure that you are using the latest nightly build and that we haven't already fixed the issue
2. If possible, tell us what nightly build you are using. In Windows, you can check the version by right-clicking Helion.exe in File Explorer, choosing Properties from the right-click dialog, and then navigating to the Details tab. The "Product Version" string shown on that tab will look something like this:

In this example, the executable was built from commit 3fb9e1.

Optimized line rendering to be fast showing the overlay with large maps.
Optimized and fixed an issue in the bsp traversal for marking lines the player has seen.

Fixed dehacked issue that was causing null frames to pull in custom Helion frames causing undefined behavior and potential crashes.
Fixed large hud numbers to used "0" image as the basis of fixed width to better match original doom behavior.
Fixed monster movement issue where it would attempt to move on top of another entity if it's z positions was exactly equal to the top of the other entity.

0.9.3.0

Upgraded to .NET 8
Improved build processes. (#571)
Helion will attempt to read Steam registry path on Windows for IWAD detection. (#572)

Performance improvements in flat/line rendering calculations. Significantly improves performance for maps that have a lot of dynamic rendering.that includes moving sectors, scrolling lines and floors.
Performance improvements in sight and shoot traversal.
Performance improvements in sprite rendering.
Performance improvements on static geometry rendering where options are packed into a single float to get the size in a more optimal size range for GPUs.
Performance improvements with monster movement and improvement for 3D checks when things overlap in the 3D space, e.g. cacodemons stacking on top of each other.

Fixed two-sided lines not seen on automap to match one-sided color.
Fixed dehacked text parsing to include newlines for text screens when the line was empty.
Gibbing damage set to 10000 to match doom behavior. Was causing performance issues in Smooth Doom 21 that would prevent gore from spawning when things were gibbed in this manner. (Fixes performance drop in Doom 2 in City Only MAP23 on start where monsters are in kill sector)

0.9.2.9

Added savedir argument to write/load saves from specified directory. Matches savedir command from GZDoom. (PR 564 from 72hr)
Added use original doom explosion behavior compat option. Disables all z checking for all explosions and not just things flagged with OLDRADIUSDMG.

0.9.2.8

Fix for randomized blood states to offset using the hard-coded dooms state when using a dehacked file. This would cause modified blood states to render incorrect sprites.
Fix to not apply weapon offset to it's flash state.
Fix options text header when scrolling in the options menu.

Fixed get next lowest ceiling for sector movement incorrectly returning the current floor value when none is found.
Fixed friend flag to correctly look for enemies using count kill flag.
Fixed wind/push specials that were incorrectly ignoring when other sector effect flags were set.
Fixed to add max movement check for velocity. This would previously cause the player to move beyond 30 map units per tick on fast scrolling floors.
Added short when hitting a teleport to stop checking crossed special lines to match original doom behavior. Fixes twogers MAP04.
Added compatibility option for Doom 2 projectiles activating certain walk specials.
Fixed hitscan functions using zero damage as a test flag. Fixes twogers RNG generator things firing bullets with zero damage to activate lines.

Fixed archvile fire to not be interpolated. Fixes archvile not being visible in certain cases especially when moving towards the archvile.
Added check for closet monsters to use their default movement speed if they failed to move. Fixes cases where they are in tight areas and will not trigger a teleport line.

Implemented check for OpenGL 4.4 to force using GL_MAP_PERSISTENT_BIT in glMapBufferRange. NVidia cards would automatically pin the memory. Certain AMD cards (Vega series) would not automatically do this causing FPS drops because of memory synchronization. Will fall back to OpenGL 3.3 if not supported by the GPU.
Optimized sound traversal for noise alert to prevent frame drops when firing.
Implement transfer heights logic for wind/push sectors to match boom behavior.
Implemented friendly flag in map things to be set.
Implemented the fuzz amount to be configurable. The fuzz effect is now uniform across screen resolutions and is projected across all distance from the camera. Previously it would appear more blocky as the camera is further away from the fuzz thing.

Implemented compatibility for mid texture hacks that will automatically be applied to emulate the transparent floor/ceiling effects in KDiKDiZD.

Implemented fuzz effect on player weapon sprite.
Implemented compatibility flag for vanilla movement physics. Emulates preserving momentum when running into other things.

Sector movement sounds are no longer played from self-referencing sources.

Fixes for intermission drawing offsets.
Fixed large HUD number rendering to be fixed width to match original position rendering.
Fixed crash that can be caused by single line comment characters inside quoted strings.
