[Solved] How to zoom in camera smoothly

I only want to use change camera zoom event and Time delta () to zoom out until the camera value is 0.5. But I am trying for 1 day I saw many tutorial in youtube but still I failed to do that.Any help will be thankful. To help to understand,
I want when my player is in distance with an apple of 200 pixel camera will zoom out to help to see the tree.But after I eat the apple it will zoom in to normal size.I know how to do that but it zoom in and out so fast. I want to make the zoom smooth.

a timer + a variable to control the camera’s zoom parameter isn’t work?

I don’t know how to make zoom in or out by the timer.Can you help me?

I think you are done with the timer part, just the default zoom speed is too fast for you. but if you start from the beginning, I recommend to your attention this complete video tutorial from gamevisualz Full Tutoiral How To Make interactive camera zoom Gdevelop 5 - YouTube. this is a complete guide to how to do the camera zoom, and he show how to adjust zoom speed.

Use lerp() function

lerp will interpolate values in a interval of time with TimeDelta()

lerp(valueStart, valueEnd, TimeDelta())

take a look on “bouncing-ball-and-rope” example
