BGE How to make text appear when winning or losing a game? I'm creating a game in the BGE. I want to make a message appear when the player reaches an object which is supposed to be the winning way out of the game.
I also want to make another message pop up when the player reaches a plane I've created and loses the game. Should I should use the collision sensor and then the Message actuator? But how do I make the message pop up on the screen?
The Message Actuator works with the Message Sensor to send messages between objects in the game, not to send messages to the player. To show text to the player you need to show a text object or an object that has text as part of it's material, you can also use a scene as an overlay to present the text as part of a HUD.

You could use the messaging system to have an exit sign object become visible by having it change it's visibility when it recieves a message.
