Question

I’m trying to make a game where the bullets can fly in any direction. I would ike to make them vectors with a direction and magnitude to make them go the direction. I’m just not sure how to implement this?

Thanks

Answer 1

There are two parts that need to be calculated. First, I’d start off with the total distance. This should be straightforward:

total_distance = velocity * time

Assuming this is a 2D game, you should then use sine & cosine to break the total distance up into the X and Y components (for a given angle):

distance_y = total_distance * sin(2 * pi * angle / 360)
distance_x = total_distance * cos(2 * pi * angle / 360)

Finally, the distance x/y should be offset based on the starting position of the bullet:

pos_x = distance_x + start_pos_x
pos_y = distance_y + start_pos_y

Of course, you could wrap all of this in a nice class, expanding & polishing as needed.
