arcBoxCollision(params)

The arcBoxCollision method is a specialized function within the Collision class designed specifically for detecting collisions between an arc-shaped entity (potentially representing the player) and a rectangular box-shaped entity (potentially representing a wall) in the game world.

Parameters:

• arcX (number): The x-coordinate of the arc entity.
• arcY (number): The y-coordinate of the arc entity.
• rectX (number): The x-coordinate of the box entity.
• rectY (number): The y-coordinate of the box entity.
• size (number): The size of the box entity.
• radius (number): The radius of the arc entity.

Logic:

1. Distance Calculation:

    const distX = Math.abs(arcX - rectX - size / 2);
    const distY = Math.abs(arcY - rectY - size / 2);
   

   • The method starts by calculating the distance between the center of the arc entity and the center of the box entity along both the x and y axes.
2. Overlap Check:

    if (distX > size / 2 + radius || distY > size / 2 + radius) {
      return false;
    }
   

   • It then checks if the distance along the x-axis is greater than the sum of the sizes of the arc and the box. If true, there is no overlap along the x-axis, and the method returns false.
   • Similarly, it checks if the distance along the y-axis is greater than the sum of the sizes. If true, there is no overlap along the y-axis, and the method returns false.

3. Collision Check:

   If the above conditions are not met in the overlap check, the method proceeds to check for collision in more detail:

    if (distX <= (size / 2) || distY <= (size / 2)) {
      return true;
    }
     
    const dX = distX - size / 2;
    const dY = distY - size / 2;
     
    return (dX * dX + dY * dY <= (radius * radius));
   

   • If the distance along the x-axis is less than or equal to half the size of the box, there is a collision along the x-axis.
   • If the distance along the y-axis is less than or equal to half the size of the box, there is a collision along the y-axis.
   • It performs a circular collision check to ensure the arc does not intersect with the corners of the box.
4. Result:
   • If any of the collision conditions are met, the method returns true, indicating a collision between the arc and the box. Otherwise, it returns false.

Purpose:

The primary purpose of this method is to determine whether an arc-shaped entity, such as the player, is in collision with a box-shaped entity, such as a wall. It takes into account both the size of the box and the radius of the arc, ensuring an accurate collision detection mechanism that considers the geometry of the entities involved.
