A Physics doubt with speed and angle

Get help using Construct 2

Hello Everyone,

Actually I am trying a basketball free throw 2d game. A simple character in the right, and the basket in the left end. My questions are...

1. When I mouse click or touch in the screen, the ball should comes towards my clicking position.
2. Based on how far and close I am clicking from the player, the ball should be fast and slow.

Thanks in advance.

I have attached a rough example using the physics engine. When you click on the screen it will throw the ball towards your mouse, and the farther away you click the more force it will give the ball.

Let me know if you have any questions!

I missed one thing! Click on the ball and set the collision mask to "circle". Otherwise it will try to collide like a square and act a little silly.

I used a simple distance calculation:
distance(Mouse.X,Mouse.Y,Ball.X,Ball.Y)

This will set the force directly to the distance from where the mouse was clicked (Mouse.X and Mouse.Y) to where the ball currently is.

You can adjust this force by multiplying it afterwards if you want.

Half the force: distance(Mouse.X,Mouse.Y,Ball.X,Ball.Y) * 0.5
Double force: distance(Mouse.X,Mouse.Y,Ball.X,Ball.Y) * 2

Awesome n tanx

Now I am trying it as a bullet. Created a simple canon and a bullet ball. Applied every actions to that bullet ball, but it is not working properly.

HOW TO DO THIS -

I want that canon to shoot a bullet with variable speed based on the distance of my mouse click.

If i remove the Physics force distance cmd and add

"Bullet-->Set bullet speed to Mouse X" it works fine. When I keep my mouse close enough to canon and click, the speed is less and if i click far away from the canon, the speed is quick.

BUT THIS IS ONLY FOR X

Ok. If i add Y "IT IS NOT WORKING"

Help me here Please...

As I am testing in Mobile, when I change the mouse X and Y to Touch X and Y, the Bullet angle and speed does not work properly.

Where ever I touch, I goes in the same speed.

Why??

Thanks in advance
