Platformer walljumping when I don't want it to

So I'm kinda new at this and trying to make a simple platformer noscript and I've gotten pretty close to what I want. Issue here is that when the character touches a wall instead of falling it just levitates midair, which allows for it to basically save from every fall by walljumping. Help?

{
//Movement
public float speed;
public float jump;
float moveVelocity;
public Rigidbody2D rb;
bool isGrounded;

void Update()
{
//Grounded?
if (isGrounded == true)
{
//jumping
if (Input.GetKeyDown(KeyCode.Space) || Input.GetKeyDown(KeyCode.UpArrow) || Input.GetKeyDown(KeyCode.Z) || Input.GetKeyDown(KeyCode.W))
{

GetComponent<Rigidbody2D>().velocity = new Vector2(GetComponent<Rigidbody2D>().velocity.x, jump);
}

}

moveVelocity = 0;

//Left Right Movement
if (Input.GetKey(KeyCode.LeftArrow) || Input.GetKey(KeyCode.A))
{
moveVelocity = -speed;
}
if (Input.GetKey(KeyCode.RightArrow) || Input.GetKey(KeyCode.D))
{
moveVelocity = speed;
}

GetComponent<Rigidbody2D>().velocity = new Vector2(moveVelocity, GetComponent<Rigidbody2D>().velocity.y);

}
void OnCollisionEnter2D(Collision2D col)
{
Debug.Log("OnCollisionEnter2D");
isGrounded = true;
}
void OnCollisionExit2D(Collision2D col)
{
Debug.Log("OnCollisionExit2D");
isGrounded = false;
}
}

How can I make a background?

Hi, i'm a beginner on Unity and I'm sure how to make a background/map. I've seen a few tutorial about doing a tilemap, but everytime i do this, the tilemap overlap my character, so i'm not sure where i can look to make the character overlap the tilemap/background?
Btw srry for my bad english, its not my first language😅
Thx.

I put a great big Akira inspired freight elevator in my game about a quantum cat. It really helps sell the scale of the environments.

What open source projects have you been a part of? Is it still active?

Hello everybody

I've been wanting to contribute to open source projects to sharpen my skills, but haven't found anything yet. wanted to see if you guys have been a part of the game dev open source community.
would love to hear about your experience

Made a fire stream out of symbols. Does it look good? Current battle gameplay: everything shoots automatically. You just reload, maybe craft something mid-fight (like a shield or a support drone) and escape in time. Still deciding if I should rework it to give the player more control...

2D Platform Game for School Project... NEED HELP

Hey guys, this is my code in C# that i actually got from chatGPT because im not really good in coding haha... The problem is that for player2 (frog) it is not actally reseting horizontal velocity only after landing but its like allways... and if there is no reseting of horizontal velocity the frog is sliding after landing.. Can anybody help me with that somehow?
