Spawning endless encounters


We need at least three encounters to endlessly cycle and create a never-ending world; two can be on the screen at any one time and a third positioned ahead of the player. We can track Pierre's progress and reposition the encounter nodes ahead of him.

Building more encounters

We need to build at least two more encounters before we can implement the repositioning system. You can create more if you like; the system will support any number of encounters. For now, add two more SpriteKit Scene files to your game: EncounterB.sks and EncounterC.sks. Resize these scenes to 900 wide by 600 tall, like EncounterA. You can fill these encounters with bees, blades, coins, and bats - have fun! Make sure to assign the custom class attribute to the sprites that you drag into the scene editor.

For inspiration, here is my EncounterB.sks:

Here is my EncounterC.sks:

Tip

For perfect alignment with the ground, place your Blade sprites at -224 on the Y-axis.
