How to use Ease?

Help Requests
1

In my game, I have a red block that I want to move up 3 spaces when A is pressed, but only once. I’ve got it set up to where it does just that, but I want the movement to ease, or transition, instead of being an automatic jump (my idea is to have it be a rising platform). I’m not sure how to do this, but I think it requires the Ease function? I don’t know how Ease works, so if anyone could give me pointers on how to use Ease for this purpose, it would be much appreciated.

Hey @goodberry - you have the right idea, I think an Ease block is what you want.

The Ease block is documented here: http://flowlab.io/behavior_handbook/#logic-math-ease

The basic idea is that when you send two values into it, it will “Ease” from one value to another. You’ll want to do something like this:

  1. Send the red block’s starting y position into the “from” input
  2. Send the red block’s ending y position into the “to” input
  3. When both inputs are received, the Ease block will start generating output values
  4. Send the output value into the red object’s y property

You can delete your behaviors, then copy this, click the behavior window, select “import”, and paste it in:

Thank you! That’s really cool, and I think understand it now, and it worked. What would I need to do to make this action perform only once?

You can add a switch after the Keyboard block, and turn the switch off after it triggers once.
