Zoom in/out

Hello everyone i have question about how to zoom in/out in specific point like at mouse position ?

You can change the scale of a layer and use the ScrollTo behavior to set the focus.

i did it but i cant change speed of scrolling

Scrolling speed is very custom kind of thing. Your going to need to figure it out. however here is the basics.

startScale

endScale

EveryTick

If( layoutscale != endScale )

layoutscale = lerp( startScale, endScale, lerpValue between 0-1)

and for scrolling

My suggestion is to

make a camera target object

make a camera object. Attach ScrollTo behaviour to the camera object.

move the camera target object to where you want.

Evertick

if camera target is not overlapping camera object

cameraveObject.moveTowards XY of CameraTarget of speedInPixels * dt

Magicam is a great plugin for doing all kinds of camera related movments. check it out in the plugins section

Use a global variable Zoom.

Zoom = 0 ----- set layout scale to : lerp(layoutscale, 0.4, 1*dt) .... this zoom out

Zoom = 1 ----- set layout scale to : lerp(layoutscale, 1.5, 1*dt) ....... this zoom in
