2D Endless runner - suggestions for logic to control randomly chosen prefabricated floor sections

bruceherbert

Hi All,

I am making an endless runner that has randomly chosen prefabricated floor sections. (I want to make a selection of floor sections which are then chosen as the game gets more difficult and they can be more challenging)

Just wondering the best way to approach it. My thinking was: each prefabricated floor section controls itself it moves itself across the screen from right to left it emits a signal before it goes off the screen left (and is no longer needed) it destroys itself after that

upon receiving the signal, a parent node loads a new prefabricated floor section off screen right

I am wondering how to set up the signals and connect them on randomly chosen then instanced pieces.

Unless there is a much better way - this may be totally not the way to do it...

Thanks

The 3d endless runners I've seen, you run straight into the sections not left to right. Is it 2d or 3d? What about the sections? Do they have moving objects on them or are they all static? I think I would have a base class that took care of sending signals, placement, etc. The sections would inherit from it. They would probably have to be all the same size to get the placement right. You might could use a VisibilityNotifier to tell when they were not seen by the camera.

Hi, thanks for the reply. This one is a 2d runner. The pieces are all one screen width in size. I took your advice to have a base class. They are able to work out where they are and remove themselves. I have a signal which is emitted, but the main scene doesn't seem to respond to it for some reason. This is the last bit to get going - e.g. adding the next piece onto the screen. Any suggestions for what I might be doing wrong on the signals would be great.

Well, there are two ways to connect a signal. You can use the editor, or you can use code. If you use the editor, you first declare your signal, then you go in the nodes tab on the far right, and you connect it to another script. Otherwise you can use code. There is a pretty good explanation here: https://kidscancode.org/blog/2017/03/godot_101_07/

Yes! That did it:) Not sure why it never occurred to me to connect the signal when creating the instance:) Thanks so much:)
