Half-Life Featureful SDK 2026-06-11

This release includes:

• The mod sample with all needed assets and demo maps.
• The dev-only package that includes only updated game libraries and FGD.
• The apk for Android (you'll need to manually put the featureful mod folder in your Android Xash3D-FWGS installation)
• Custom FGD provided by the community with related assets (like entity-specific icons and models) that might help the level designer.

Note: zhlt entities are not included in the FGD. You must add zhlt.fgd to your game profile configuration in the map editor.

If you already have a mod in development based on Half-Life Featureful read this article to get the idea how to apply the new SDK version for your project.

Changelog

Bugfixes

• Zoom crosshairs are no longer drawn on the unscoped weapon if default_fov is less than 90 (original Half-Life bug). Thanks @Ambient-Impact for reporting.
• Restored the default target monster search delay on scripted_sequence to 1 second (as it was in Half-Life). This was accidentally changed to 0 seconds in 2026-01-22 version and may have potentially led to performance issues.

Entity templates

• Added detonate_on_touch property for projectile entity templates to allow making hand grenades detonate on touch.

Weapon templates

• Added viewmodel_beams property for weapon fire to allow drawing beams attached to the view model on weapon firing.
• projectile property is now partially supported for weapon_handgrenade.
• In-place "ent_template" definitions are now allowed for projectile.

Weapons

• weapon_displacer now cancels its attacks on holster.
• weapon_displacer beams are playing client-side now.

JSON configuration changes

• Parsing object properties now checks for key duplicates and reports the error if there's a duplicate.
• "scale" , "framerate", "life", "noise" and "scrollrate" properties in visuals are now required to be non-negative numbers.
• "framerate" property in visuals now supports ranged values.

Sample mod changes

• Updated dmc nailgun and supernailgun to use in-place entity template definitions for projectiles.
• Fixed dmc nailgun using wrong speed for nails.
