Procedural Generation: Endless Runner Unity Tutorial (Updated 2023)

Hey friends! Let's learn how to generate infinite levels and platforms in Unity with Procedural Generation! This is a follow-up to a video I made about Subway Surfer, and I thought this would be a good overview on how procedural generation works.

Thanks for the tutorial!

If anyone have already have forward running character, or you don't want the platforms that sliding backward, you can try this:

Mine SectionTrigger from this tutorial script looks like that:
public class SectionTrigger : MonoBehaviour
{

public float moveStep; //lenght of platform offset on trigger = full exact lenght of platform(fills from inspector)
public int stepCount = 0; //multipler for each next offset(counter of triggers)

public GameObject roadSection;

void OnTriggerEnter(Collider other)
{

{
stepCount += 1;
Instantiate(roadSection, new Vector3(0, 0, moveStep * stepCount), Quaternion.identity);
}
}
}

Your videos are really nice and helpful, I believe the curve World effect helped me solve a problem in my game. But actually in Subway Surfers the character rather moves instead of the world. I’ve been able to move the camera in the game away from the character and can confirm that the player rather moves which is what I’ve been doing in my game. But this tutorial was actually really interesting, good vid.

Hey, i have a problem. i have a section that has a box collider and when the player triggers the box collider, the box collider will deactivate and spawn a new section, but after it spawns a section, the new section it spawned doesn't work anymore, in which the box collider in the new section isn't activated, this is because the prefab is using itself and changes itself, but i don't want that to happen and i don't know how to fix it.

When the road section is destroyed I get a MissingReferenceException
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
If I check for null then my SectionTrigger stops working.

Just underneath the heart on your icon you need to put the letter "S" because you are SUPER!!!

Train of thought

How to apply this to rimworld,
A planet like venus with a long day,
Wait what about that planet in riddick that was a blazing inferno and you had to keep moving to avoid death
So like procedurally generated surface on extremely slow rotation planet but the topography does repeat eventually.

Can we get a possible update/re-go over of this? a bit slower, more in depth/detailed? with better steps some feel like they were skipped over. I tried this and the script just seemed to not work at all for me.

[NooB.]

Can you add random cat generate on? pls

[SAJJAD-dhxp]

How do we fix gap between new tiles just instantiated?! And im increasing speed but gap appear

[VeryTori]

When I add the RigidBody to the road prefab, the sections push each other up or down if you look at the scene from a side view. How can I fix this?

[heytsla]

i want to, like generate new platforms rather than same one ? can anyone help

[akRedmage]

Do you have any issues with Z-fighting when you spawn the prefabs over each other, or is that something you fix later?

[tgerm]

The destroy wall is not working for me
