I have been making a brick breaker game in Unity in 2D as my first game. I have got the ball bouncing off the paddle correctly and can bounce it of the paddle at different angles. However, when the ball hits a wall or the roof it always bounces so its either traveling exactly in the X-directon or Y-direction regardless of what angle it hits the wall with instead of bouncing off at 90'.
Im not using any scripts to control the bouncing off the walls or roof just using 2D box colliders on the roof and walls (which are cubes) and a circle collider and 2D rigidbody on the ball (sphere) which Ive given a bouncy material.
Any help would be really appreciated.
