Running multiple methods at the same time in java fx

Question

HI I AM LEARNING JAVAFX AND I AM USING SCENEBUILDER. IN MY GAME I NEED TO LOCATE THE POSITION Of the BALL AT ALL TIMES HOWEVER THIS REQUIRE MULTIPLE METHODS RUNNING SIMULTANEOUSLY. I KNOW THAT USING THREADS DO THIS BUT I AM THINK I AM USING THEM WRONG. THE PROBLEM COULD ALSO BE WITH THE BALL.CENTERYPROPERTY.GETVALUE METHOD. IT IS CONFUSING AS IT APPEARS THAT THE BALL.GETY RETURNS A DIFFERENT VALUE TO BALL.CENTERYPROPERTY. PLS HELP. I AM STILL LEARNING SO MY CODE IS NOT THE NEATEST.

SORRY ABOUT THE CAPS MY KEYBOARD IS GLITCHING 😐

THIS IS MY JAVAFX CONTROLLER CODE AND MAIN CLASS

Answer 1

The problem is the two stages never update simultaneously. I think they both are using the same javafx Application thread in Platform.runLater.
