The balls is not heading directly

I notice that the mouse clicks anywhere the balls will go that way. But when I try to click on the corner of the screen The destination of the ball is only in the square. https://gotm.io/abczezeze/shoot-only-gdsc

how to the ball is heading directly along mouse clicks position.

I didn't know how to fix it, So I will modify my mini game project by limit the area to shoot the ball.

Perspective camera probably related to move the balls, I guess

Every ball that doesn't hit one of those cubes seems to be flying perfectly straight to me.

update a little add source code and took a note (Thai language) on my web blog

I think I get it. You want the ball to be able to be aimed toward the two walls and bounce and hit more objects right? But the area the mouse can click is a square. It’s square because we have square screens. The click info from touching a 2d surface is not enough to define 3d vectors going in more than one z direction.

Have you ever played air hockey? You might want to try to use a swipe to guess a little more about the player’s intended direction.

Thank you for the guideline and sorry i'd like to use this style for my game. Really thank you.

I can't see your code, but you have to change the velocity of the ball. It looks like you are just moving it forward (on the z axis) so it is always going to move forward. You need to give it a Vector3 with the x and y of the mouse position (and z would be the same speed you have now).

If this game is on the phone, maybe you could move the phone around to move the camera. Then the ball just needs to shoot in the direction of the camera when you tap on the screen.

My source code on Github. I try change to orthogonal camera my game seem 2d game but the ball can fly directly every mouse position click. I check this out but I'm a Slacker Game Developer. Sorry and Thanks.

This line in your ball script is making it go straight forward:

apply_impulse(Vector3(rand_range(-10,10),rand_range(-10,10),rand_range(-10,10)),Vector3(0,0,-15))

The last vector is just moving along the negative z, so will always move straight:

Vector3(0,0,-15)

You need to make a function on the ball that accepts the mouse position from the main script (at the time when you instance it). Then when it moves it would move based on the x/y of the mouse, not 0, 0.

I couldn't figure it out what's the x/y value. I search and find the resolve by this and fix it to

apply_impulse(Vector3(rand_range(-10,10),rand_range(-10,10),rand_range(-10,10)), global_transform.origin*5)

Thank you so much @cybereality

Yeah, no problem.
