Generating Random Obstacles | MAKING AN INFINITE RUNNER game like CANABALT #5 | Unity Tutorial

Adding a bit of difficulty by spawning obstacles on top of the procedurally generated platforms, and of course, running into them.

Wow man, I didn't know you had your own channel separate to Super Game Bros. Subbed and great Tutorial

[riuzakyrodriguez]

you saved my homework man, great series

[DevNoob]

Think. Code. Drink. What a great order man! I've been wanting to make an infinite runner for a while now...

I love your tutorials. but i have a little problem to the height of buildings... they height is so similar and this makes the game very easy. ( i don't create obsacles yet)
Here's my code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Ground : MonoBehaviour
{
Player player;

public float groundHeight;
public float groundRight;
public float screenRight;
BoxCollider2D collider;

bool didGenerateGround = false;


private void Awake()
{
player =
collider =
groundHeight = transform.position.y + (collider.size.y / 2);
screenRight = Camera.main. transform.position.x * 2;
}


void Start()
{

}

// Update is called once per frame
void Update()
{

}

private void FixedUpdate()
{
Vector2 pos = transform.position;
pos.x -= player.velocity.x * Time.fixedDeltaTime;



groundRight = transform.position.x + (collider.size.x / 2);

if (groundRight < -22f)
{
Destroy(gameObject);
return;
}

if (!didGenerateGround)
{
if(groundRight < screenRight)
{
didGenerateGround = true;
generateGround();
}
}

transform.position = pos;
}

void generateGround()
{
GameObject go = Instantiate(gameObject);
BoxCollider2D goCollider =
Vector2 pos;

float h1 = player.jumpVelocity * player.maxHoldJumpTime;
float t = player.jumpVelocity / -player.gravity;
float h2 = player.jumpVelocity * t + (0.2f * (player.gravity * (t * t)));
float maxJumpHeight = h1 + h2;
float maxY = maxJumpHeight * 0.7f;
maxY += groundHeight;
float minY = 9;
float actualY = Random.Range(minY, maxY);

pos.y = actualY - goCollider.size.y / 2;
if (pos.y > 7)
pos.y = 7;

float t1 = t + player.maxHoldJumpTime;
float t2 = Mathf.Sqrt((2.0f * (maxY - actualY))) / -player.gravity;
float totalTime = t1 + t2;
float maxX = totalTime * player.velocity.x;
maxX *= 0.7f;
maxX += groundRight;
float minX = screenRight + 5;
float actualX = Random.Range(minX, maxX);

pos.x = actualX + goCollider.size.x / 2;
go.transform.position = pos;

Ground goGround = go.GetComponent<Ground>();
goGround.groundHeight = go.transform.position.y + (goCollider.size.y / 2);
}
}
p.s my canvas is a little smaller than yours and in another position.

I got this bug where I am colliding with the obstacles but some obstacles does not disappear or slowdown my character. I do not know what is causing this bug I triple checked my code I coded it right. If anyone can help it would be great!

[justVisfine]

I'm having an issue where the obstacles are generating at heights generated by the previous platform, causing them to generate either in the platform or above it. any suggestions?

[rd_dimensional]

someone pls help! When it comes to the boxes sometimes my player just runs right through them. I have no idea what causes it and it seems to just happen randomly. Does anyone at least know what I can check or look out for to fix this. thx

[iloveabg]

My code was identical to yours, but way too many boxes where spawned and some were floating. How could i fix this? Thanks.

[TheSzymonc]

Small bug there, when you land on obstacle player falls down (never made contact with ground I guess)

Don't be stingy ! Give us the script in description link.or else I have no reason to subscribe to your channel. There are 1000s of game dev teachers in youtube
