Drag and Drop Custom Blocks on UIAxes in MATLAB

Hello. I'm trying to build an app on the MATLAB App Designer. The app is about Path Planning and Path Following of a Ground Vehicle. The thing is that in the Path Planning Algorithm, I want to add certain Obstacles (explained in the figure below), and then the algorithm will find the optimal path accordingly.

What I want is to make these movable. Or maybe to pick and drop from a sidebar? Is it possible to do so that I can place obstacles wherever I want?

Hi Fawad,

I understand you want to add movable objects in the UI axes.

Can you let me know that do you want them to move randomly or based on some mouse movement or key press?

"What I want is to make these movable. Or maybe to pick and drop from a sidebar? Is it possible to do so that I can place obstacles wherever I want?"

All of those things are possible. You will need to define the UIFigure's WindowButtonDownFcn, WindowButtonMotionFcn, and WindowButtonUpFcn. See the "Window Callback" section of this page: https://www.mathworks.com/help/matlab/ref/matlab.ui.figureappd-properties.html

Good luck!
