Title: Bullet Face direction problem
Post by: Jan666 on May 27, 2022, 08:04:33 am

Hello, i need a solution for a 2d shot game. The player still shot to the right direction, i have no idea how i change the bullet direction when he walk to the left side?

//Touch Shot Button
if(btn.btnRect3.contains(worldPos)){
                                                                       
                           isFiring = true;      
}


//bullet shot details

if(isFiring == true){
       
        bullet newBullet (Vector2f( 20, 20));
        newBullet.bulletSetPos(Vector2f(player.playerSprite.getPosition().x  + 60, player.playerSprite.getPosition().y + 100));
        bulletVec.push_back(newBullet);
        isFiring = false;
   }



 

Any Ideas

Do you mean to bullet travels in the wrong direction or the player faces the wrong direction?

I search something that turn the following values into negative values when the player turns left

The player.playerSprite.getPosition().y + 100)) < -- the 100 have urn into - 100

newBullet.bulletSetPos(Vector2f(player.playerSprite.getPosition().x  + 60, player.playerSprite.getPosition().y + 100));  


 

An the move value 3 have to turn into -3

bulletRec.move(0, 3);

 

For the players face direction i used setScale(3, -3 ) and setScale (3, 3)
