I am trying to pause the simulation of cars with a space key input and again resume the simulation when a space key is pressed. I have tried using waitforbuttonpress and pause function but it pauses but does not resume. This has to come inside a while loop to wait for the buttonpress and check if it is space.

Hello Karthikeyan,
In order to pause a simulation upon occurance of an event, callbacks can be leveraged. In this scenario the simulation needs to be paused once 'space' bar is pressed. You could use 'WindowKeyPressFcn' callback of the figure block in order to detect whether the space bar is pressed or not and there by pause the simulation. The callback can be written as follows:
function buttonCallback(src, event)
val=event.Key; % Key property contains the details of the key which was pressed
if val=='space'
disp('Space Pressed. Pausing...')
pause(5)
end
end
The modified code is attached. For more information regarding callbacks you could have a look at the following documentation page: Callbacks Documentation.
Hope this helps!
