Fruit Ninja-like fruit movement [closed]

Question

I am creating a Game similar to Fruit Ninja and I need some help regarding random motion of fruits in my game. I already created the slice effect, but there is no random motion of sprites.

Answer 1

I would start by generating the random starting position of the item. This should be off-screen, which can be handled with a simple set of nested if statements.

Next I would generate a random direction on the screen. To make sure it will shoot onto the screen, find a random position on the screen and calculate the direction (x and y amounts, similar to slope) from the starting point and target point.

Once you have a position and direction, then you just need to give the objects a velocity proportional to the direction vector. Every frame you will decrease the y velocity to simulate gravity and the object will travel in an arc.

This is a fairly simple algorithm, although you might need to change the target point, specifically changing the y value to a high location.
