How do Power Bar

Hi,

I want to make pawer bar working like in picture

The red block moving from left to right continuously. It's like a refleks game, when player have to hit in right moment to get a biggest number. How to made it?

There are so many ways to make something like this it all depends on what you'd like to do with it..

Which part of this do you have difficulties with?

The red block moving from left to right and back can be done with many movement behaviours

Stopping the movement on space bar shouldn't be hard..

Comparing the position of the red sprite and determining it's distance from either 1 or 25 to get the right value could be done by comparing the x-position or distance
