Sentido de vias

Hola a todos, estoy desarrollando un Juego de vehículos en el cual tengo que verificar la dirección de las vias, mi caso es el siguiente:

Tengo vías de doble sentido y necesito que el juego me mande una advertencia cuando el vehículo que estoy conduciendo este yendo en sentido contrario.

Alguien me puede ayudar?

existe algún control o artificio para hacerlo?

I have a two-way game and I need you to send me a warning when the vehicle I am driving this going the wrong way.

Please, this is an English forum, try to stick with it, or at least always provide a translation with your topics.

Do a research about car games/tracks/checkpoint, I remember there were examples around, can't remember exactly if those were in the tutorials or the forums though.

I added a translation to your original message and moved your topic.
