Hello Kyle,
I understand that you want to draw the rooms (rectangles) in app designer such that none of them overlap. To achieve this, we must provide information like length, width, and position of the room to the rectangle function which you have used.
Additionally, to access the room when the user enters it, we can store the references to these rooms in an app property rooms which is an array. Each of them can be accessed using the index number equal to the order in which they are created.
For a sample demonstration of this process, kindly refer to the following steps:
- The Create Room button uses a callback to create the room with the desired properties given as input.
- The Highlight Room button uses a callback to change the edge colour of a room using its index.
properties (Access = public)
rooms = [] % Description
end
% Callbacks that handle component events
methods (Access = private)
% Button pushed function: CreateRoomButton
function CreateRoomButtonPushed(app, event)
room = rectangle(app.UIAxes, 'Position', [app.X_posEditField.Value, app.Y_posEditField.Value, ...
app.LengthEditField.Value, app.WidthEditField.Value]);
app.rooms = [app.rooms room];
end
% Button pushed function: HighlightRoomButton
function HighlightRoomButtonPushed(app, event)
room = app.rooms(app.RoomNumberEditField.Value);
room.EdgeColor = 'red';
end
end
