Introduction

This page describes changes made to the default behavior of the code. This will be mostly bug fixes. We try to keep changes to a minimum. This list contains all changes that will affect the default behavior.

Limits

Increased Upgrade Limit to 1024

Code Changes

Minor Laser visual improvements

Module: LaserDraw

In vanilla ZH, a laser beam always moves along with the shooter's firebone, but the Muzzle particle system will stay in place. This has been changed. The muzzle particle system will now always move with the shooter's firebone along with the laser beam.

Fixed HelixContain passenger fireports not working

Module: HelixContainUpdate

Transports with HelixContain and fireports, now have their passenger correctly fire from the Firepoint bones

Note: This requires the transport to have the FIREPOINTXX bones. It is not enough to put them on a portable Bunker object.

Changed default behavior for Airborne collissions in PhysicsUpdate

To avoid helicopters randomly dying via a chain reaction, we changed the conditions when "VehicleCrashesIntoNonBuildingWeaponTemplate" is fired. This wepaon should be triggered when an object (i.e. a dying helicopter) crashes into a ground vehicle, but it often triggers already mid air if the object collides with airborne projectiles, lasers or dummy objects. We changed the default behavior to ignore airborne collissions.

Module: PhysicsUpdate

Changed conditions for VehicleCrashesIntoNonBuildingWeaponTemplate to be fired on non-airborne collissions only. Added new parameter to restore default behavior

  • VehicleCrashWeaponAllowAirborne = No - (restores default behavior to also trigger VehicleCrashesIntoNonBuildingWeaponTemplate on airborne collissions. Not Recommended)

VTOL Improvements

(Module: JetAIUpdate)

VTOL Aircraft = Aircraft which needs parking space in airfields but with NeedsRunway = No in JetAIUpdate.

Various fixes and improvements:

  • Add support for Jets (WINGS locomotor) to land/take off without runways. Previously only aircraft with HOVER locomotor could park/land. This requires a HOVER locomotor in locomotor set SET_VTOL.
  • Slightly changed landing and takeoff behavior of all VTOL aircraft. Vertical take off now takes slightly longer.
  • Fixed wrong parking orientation for VTOL aircraft. VTOL aircraft were turning the wrong way when reloading ammo in their parking spot. This is fixed.

Fixed Spectre Gunship getting selected for every player

Fixed issue in SpectreGunshipDeploymentUpdate causing the gunship to get selected for every player. The gunship is now selected for the controlling player only.

Fixed Decal Shadows being applied multiple times

Fixed issue for units with texture based shadows (SHADOW_DECAL, SHADOW_ALPHA_DECAL or SHADOW_ADDITIVE_DECAL) where the shadow decal is applied multiple times if the unit has multiple draw modules. Now only 1 instance of the shadow is applied.
