Project 544: Infinite Runner

4. (Group activity) An infinite game

This game is going to be endless, but manually creating endless obstacles and collectibles would literally be impossible. How would we solve this?

Steps

1. A gif of a first draft

All the obstacles are cloning endlessly now, but it's sort of predictable. How can we make the game feel more unpredictable and exciting?

2. A solution to the problem

Randomizing! In the last example, obstacles would appear every 2 seconds perfectly. In this example, they'll appear anywhere from 1 - 4 seconds randomly.
