So, i'm trying to make a game in which some a character launches an projectile (still haven't thought about it's appearance too much), to catch an object.
I created an arrow that the player uses to align the shot using the w ans s keys and when he presses space (in theory) the projectile goes to the predetermined direction.
The issue is that i couldn't manage to make the projectile to go in the respective direction, it just goes in one direction.
I'm a noob, be kind :) .

PS: i tried the method from this post, but i couldn't get it working :/ https://en.sfml-dev.org/forums/index.php?topic=16801.0
