Build v0.015c — intro map overhaul and player init rewrite

Seamless travel went in last build. This one deals with everything it broke.

Rewriting player init

A large part of the initialisation for bp_player was rewritten, and several checks added to bp_playercontroller to confirm references are still valid after a level change. This is the unglamorous foundation work that stops health, missions and HUD state from quietly desyncing every time the squad moves between levels.

Related: seamless level travel was not syncing health, and missions were getting out of sync for client players. Both fixed here.

Group spawning

BP_SpawnZombieGroup was added, so encounters can be placed as groups rather than one zombie at a time. BP_RandomVehicle was added alongside it to create random stationary vehicles with random inventories, and vehicles were reorganised into their respective maps.

Added

• Big intro map updates
• Large explosion sound for the plane bombing run (bp_explosion)
• BP_SpawnZombieGroup for spawning groups of zombies
• BP_RandomVehicle for random stationary vehicles with random inventories

Fixed

• Bullet hole decals not spawning after the WeaponFiring refactor for screen aiming override
• Missions getting out of sync for client players
• Seamless level travel not syncing health
• Animations not playing correctly for zombies on clients
• Distant zombie anim blueprint not initialising correctly

Changed

• Removed motion blur from the third person camera
• bp_missionactivator updated to cancel or complete missions
• Changed the explosion type for landmines
• Changed the explosion type for C4
• Police, ambulance and fire trucks no longer cause camera zoom when standing close by
• Structured vehicles into their respective maps
• Updated redirectors
