Pawn, the base class of all actors that can be controlled by players or AI.

Pawns are the physical representations of players and creatures in a level. Pawns have a mesh, collision, and physics. Pawns can take damage, make sounds, and hold weapons and other inventory. In short, they are responsible for all physical interaction between the player or AI and the world.

Functions

Native functions

ForceCrouch

native function ForceCrouch ()


GetBestAnchor

native function NavigationPoint GetBestAnchor (Actor TestActor, Object.Vector TestLocation, bool bStartPoint, bool bOnlyCheckVisible, out float out_Dist)


GetBoundingCylinder

native function GetBoundingCylinder (out float CollisionRadius, out float CollisionHeight) const

Overrides: Actor.GetBoundingCylinder


GetTeamNum

simulated native function byte GetTeamNum ()

Overrides: Actor.GetTeamNum


GetVehicleBase

native function Vehicle GetVehicleBase ()


InitRagdoll

native function bool InitRagdoll ()

Does the following: - Assign the SkeletalMeshComponent 'Mesh' to the CollisionComponent - Call InitArticulated on the SkeletalMeshComponent. - Change the physics mode to PHYS_RigidBody

IsHumanControlled

simulated final native function bool IsHumanControlled ()

IsHumanControlled() return true if controlled by a real live human on the local machine. On client, only local player's pawn returns true

IsInvisible

native function bool IsInvisible ()

Returns:

true if pawn is invisible to AI

IsLocallyControlled

simulated final native function bool IsLocallyControlled ()

IsLocallyControlled() return true if controlled by local (not network) player

IsPlayerPawn

simulated native function bool IsPlayerPawn () const

IsPlayerPawn() return true if controlled by a Player (AI or human) on local machine (any controller on server, localclient's pawn on client)

IsValidEnemyTargetFor

native function bool IsValidEnemyTargetFor (const PlayerReplicationInfo PRI, bool bNoPRIisEnemy) const

Returns if this is a valid enemy for PRI. Checks things like whether the Pawn is alive, teammates, etc. Works on clients and servers.

Native implementation:

UBOOL APawn::IsValidEnemyTargetFor(const APlayerReplicationInfo* OtherPRI, UBOOL bNoPRIIsEnemy) const
{
        // only am valid target if not dead, and not driving a vehicle
        if ( bDeleteMe || (Health <=0) || DrivenVehicle )
        {
                return FALSE;
        }
        if ( !PlayerReplicationInfo )
        {
                 return bNoPRIIsEnemy;
        }
 
        // and not on same team, or neither is on a team (which implies not a team game)
        return !OtherPRI || !PlayerReplicationInfo->Team || (PlayerReplicationInfo->Team != OtherPRI->Team);
}

IsValidTargetFor

native function bool IsValidTargetFor (const Controller C) const

returns if we are a valid enemy for C checks things like whether we're alive, teammates, etc server only; always returns false on clients

Obsolete:

Use IsValidEnemyTargetFor() instead!

ReachedDestination

native function bool ReachedDestination (Actor Goal)


ReachedPoint

native function bool ReachedPoint (Object.Vector Point, Actor NewAnchor)


SetAnchor

native function SetAnchor (NavigationPoint NewAnchor)


SetPushesRigidBodies

native function SetPushesRigidBodies (bool NewPush)


SetRemoteViewPitch

native final function SetRemoteViewPitch (int NewRemoteViewPitch)

Set Pawn ViewPitch, so we can see where remote clients are looking.

Parameters:

  • NewRemoteViewPitch - Pitch component to replicate to remote (non owned) clients.

SuggestJumpVelocity

native function bool SuggestJumpVelocity (out Object.Vector JumpVelocity, Object.Vector Destination, Object.Vector Start)

SuggestJumpVelocity() returns true if succesful jump from start to destination is possible returns a suggested initial falling velocity in JumpVelocity Uses GroundSpeed and JumpZ as limits

TermRagdoll

native function bool TermRagdoll ()

the opposite of InitRagdoll(); resets CollisionComponent to the default, sets physics to PHYS_Falling, and calls TermArticulated() on the SkeletalMeshComponent

Returns:

true on success, false if there is no Mesh, the Mesh is not in ragdoll, or we're otherwise not able to terminate the physics

ValidAnchor

final native function bool ValidAnchor ()

Is the current anchor valid?
