bCamOverridePostProcess Source code

Indicates if CamPostProcessSettings should be used when using this Camera to view through.

bConstrainAspectRatio Source code

If we should insert black areas when rendering the scene to ensure an aspect ratio of ConstrainedAspectRatio

bEnableColorScaleInterp Source code

Should interpolate color scale values

bEnableColorScaling Source code

Turn on scaling of color channels in final image using ColorScale property.

bEnableFading Source code

If we should apply FadeColor/FadeAmount to the screen.

BlendParams Source code

BlendTimeToGo Source code

Time left when blending to pending view target

bLockedFOV Source code

true if FOV is locked to a constant value

CameraCache Source code

CameraStyle Source code

Camera Mode

CamPostProcessSettings Source code

Post-process settings to use if bCamOverridePostProcess is TRUE.

ColorScale Source code

Allows control over scaling individual color channels in the final image.

ColorScaleInterpDuration Source code

Total time for color scale interpolation to complete

ColorScaleInterpStartTime Source code

Time at which interpolation started

ConstrainedAspectRatio Source code

If bConstrainAspectRatio is true, add black regions to ensure aspect ratio is this. Ratio is horizontal/vertical.

DefaultAspectRatio Source code

Default aspect ratio

DefaultFOV Source code

default FOV

DesiredColorScale Source code

Desired color scale which ColorScale will interpolate to

FadeAmount Source code

Amount of fading to apply.

FadeColor Source code

Color to fade to.

FreeCamDistance Source code

Distance to place free camera from view target

FreeCamOffset Source code

Offset to Z free camera position

LockedFOV Source code

value FOV is locked at

ModifierList Source code

List of camera modifiers to apply during update of camera position/ rotation

OriginalColorScale Source code

Color scale value at start of interpolation

PCOwner Source code

PlayerController Owning this Camera Actor

PendingViewTarget Source code

Pending view target for blending

ViewTarget Source code

Current ViewTarget

EViewTargetBlendFunction Source code

TCameraCache Source code

The actors which the camera shouldn't see. Used to hide actors which the camera penetrates.
POV:

cached Point of View

TimeStamp:

Cached Time Stamp

TViewTarget Source code

View Target definition A View Target is responsible for providing the Camera with an ideal Point of View (POV)
AspectRatio:

Aspect ratio

Controller:

Controller of Target (only for non Locally controlled Pawns)

POV:

Point of View

PRI:

PlayerReplicationInfo (used to follow same player through pawn transitions, etc., when spectating)

Target:

Target Actor used to compute ideal POV

ViewTargetTransitionParams Source code

A set of parameters to describe how to transition between viewtargets.
BlendExp:

Exponent, used by certain blend functions to control the shape of the curve.

BlendFunction:

Function to apply to the blend parameter

BlendTime:

Total duration of blend to pending view target. 0 means no blending.

AllowPawnRotation Source code

ApplyCameraModifiers Source code

Apply modifiers on Camera.
@param DeltaTime Time is seconds since last update
@param OutPOV Point of View

BlendViewTargets Source code

Blend 2 viewtargets.
@param A Source view target
@paramn B destination view target
@param Alpha Alpha, % of blend from A to B.

CheckViewTarget Source code

Make sure ViewTarget is valid

DisplayDebug Source code

list important Camera variables on canvas. HUD will call DisplayDebug() on the current ViewTarget when the ShowDebug exec is used
@param HUD - HUD with canvas to draw on
@input out_YL - Height of the current font
@input out_YPos - Y position on Canvas. out_YPos += out_YL, gives position to draw text for next debug line.

FillCameraCache Source code

Cache update results

GetCameraViewPoint Source code

Master function to retrieve Camera's actual view point. do not call this directly, call PlayerController::GetPlayerViewPoint() instead.
@param OutCamLoc Camera Location
@param OutCamRot Camera Rotation

GetFOVAngle Source code

returns camera's current FOV angle

InitializeFor Source code

Initialize Camera for associated PlayerController
@param PC PlayerController attached to this Camera.

ProcessViewRotation Source code

Give each modifier a chance to change view rotation/deltarot

SetDesiredColorScale Source code

Sets the new desired color scale and enables interpolation.

SetFOV Source code

Lock FOV to a specific value. A value of 0 to beyond 170 will unlock the FOV setting.

SetViewTarget Source code

Set a new ViewTarget with optional BlendTime

UpdateCamera Source code

Performs camera update. Called once per frame after all actors have been ticked.

UpdateViewTarget Source code

Query ViewTarget and outputs Point Of View.
@param OutVT ViewTarget to use.
@param DeltaTime Delta Time since last camera update (in seconds).
