Projectile.

A delayed-hit projectile that moves around for some time after it is created.

Properties

bBegunPlay

Type: bool

Default value: True

bNotBlockedByShield

Type: bool

if true, not blocked by vehicle shields with bIgnoreFlaggedProjectiles

bRotationFollowsVelocity

Type: bool

If true, this projectile will have its rotation updated each frame to match its velocity

Functions

Static functions

GetRange

simulated static function float GetRange ()

returns the maximum distance this projectile can travel

StaticGetTimeToLocation

static simulated function float StaticGetTimeToLocation (Object.Vector TargetLoc, Object.Vector StartLoc, Controller RequestedBy)

static version of GetTimeToLocation()

Native functions

GetTeamNum

simulated native function byte GetTeamNum ()

Overrides: Actor.GetTeamNum

Events

Destroyed

simulated event Destroyed ()

Overrides: Actor.Destroyed

EncroachedBy

simulated event EncroachedBy (Actor Other)

Overrides: Actor.EncroachedBy

EncroachingOn

event bool EncroachingOn (Actor Other)

Overrides: Actor.EncroachingOn

(Description copied from Actor.EncroachingOn)
called when this Actor is encroaching on Other and we couldn't find an appropriate place to push Other to

Returns:

true to abort the move, false to allow it

Warning: do not abort moves of PHYS_RigidBody actors as that will cause the Unreal location and physics engine location to mismatch

FellOutOfWorld

simulated event FellOutOfWorld (class<DamageType> dmgType)

Overrides: Actor.FellOutOfWorld

called when the actor falls out of the world 'safely' (below KillZ and such)

HitWall

simulated singular event HitWall (Object.Vector HitNormal, Actor Wall, PrimitiveComponent WallComp)

Overrides: Actor.HitWall

PostBeginPlay

simulated event PostBeginPlay ()

Overrides: Actor.PostBeginPlay

PreBeginPlay
