Smooth Camera

Smoothly scroll to follow an object.

Authors and contributors to this community extension: D8H.

The camera follows an object according to:

a frame rate independent catch-up speed to make the scrolling from smooth to strong
a maximum speed to do linear following (open the project online) or slow down the camera when teleporting the object
a follow-free zone to avoid scrolling on small movements
an offset to see further in one direction
an extra delay and catch-up speed to give an impression of speed (useful for dash)
position forecasting and delay to simulate a cameraman response time

A platformer dedicated behavior allows to switch of settings when the character is in air or on the floor. This can be used to stabilize the camera when jumping.

Smooth Camera

Smoothly scroll to follow an object.

Behavior actions

Draw debug
Draw the targeted and actual camera position.

Move the camera closer
Move the camera closer to the object. This action must be called after the object has moved for the frame.

Camera delay
Change the camera delay (in seconds).

Downward catch-up speed
Change the camera downward catch-up speed (in ratio per second).

Downward maximum speed
Change the camera downward maximum speed (in pixels per second).

Follow free area bottom border
Change the camera follow free area bottom border.

Follow free area left border
Change the camera follow free area left border.

Follow free area right border
Change the camera follow free area right border.

Follow free area top border
Change the camera follow free area top border.

Follow on X
Enable or disable the following on X axis.

Follow on Y
Enable or disable the following on Y axis.

Forecast time
Change the camera forecast time (in seconds).

Leftward catch-up speed
Change the camera leftward catch-up speed (in ratio per second).

Leftward maximum speed
Change the camera leftward maximum speed (in pixels per second).

Camera offset X
Change the camera offset on X axis of the object. This is not the current difference between the object and the camera position.

Camera offset Y
Change the camera offset on Y axis of the object. This is not the current difference between the object and the camera position.

Rightward catch-up speed
Change the camera rightward catch-up speed (in ratio per second).

Rightward maximum speed
Change the camera rightward maximum speed (in pixels per second).

Upward catch-up speed
Change the camera upward catch-up speed (in ratio per second).

Upward maximum speed
Change the camera upward maximum speed (in pixels per second).

Wait and catch up
Delay the camera according to a maximum speed and catch up the delay.

Behavior conditions

Camera offset X
Compare the camera offset on X axis of the object. This is not the current difference between the object and the camera position.

Camera offset Y
Compare the camera offset on Y axis of the object. This is not the current difference between the object and the camera position.

Behavior expressions

Expression	Description
`Object.SmoothCamera::OffsetX()`	Return the camera offset on X axis of the object. This is not the current difference between the object and the camera position.
`Object.SmoothCamera::OffsetY()`	Return the camera offset on Y axis of the object. This is not the current difference between the object and the camera position.

Smooth platformer camera
