Hello! I would gradually increase a numeric variable... I have a numeric Global Variable, for example equal to -300, and I want it after an event becomes equal to -600. Can I gradually pass from -300 to -600 in one second? I don't understand the lerp expression...
Thank you very much!!!
If you need to change from -300 to -600, that's actually decreasing
This should decrease X by 300 every second.
To stop after 1 second, you can either set a condition "If X>-600" or add Clamp() or Max() expression, for example:
If you want easing effects (speeding up/down etc), you can install LiteTween behavior.
You're right sorry, the variable decreases!
I thought there was something easier
Meanwhile I try with your suggestions, thanks a lot. If you also have other ideas, write
I think I've succeeded with LiteTween!
LiteTween is an overkill for this task if you just need a linear change.
X=X-300*dt is the easiest formula
If you don't care about it taking precisely 1 second, you can simply subtract 5 every tick:
At 60fps it would take approximately 1 second to decrease by 300.
You can do this with lerp if you want, but you will need another variable "t":
X=lerp(-300, -600, t)
Yes, at the beginning I tried with lerp expression.
But I don't understand the third value and therefore it didn't work.
Set X to lerp(-300,-600,0.5*dt), but the value changes immediately.
Same thing with:

"dt" is frame duration and at 60fps it's always approximately 0.016
That's why your formula always returns the same result.
You can try this:
X=lerp(X, -600, 0.5*dt)
It still doesn't work.... But I'm fine with the LiteTween, for now. Thanks for the help!
