Hi
I am wondering what is the best practice to make an Entity following another movable Entity ?

thanks

Try something like this:

I wouldn't do it this way...
calculate the distance between the two objects

sqrt(pow(player.x-my.x,2)+pow(player.y-my.y,2))


and let him look at the player.
if the distance is bigger than (for example) 20 make him move until the distance is smaller than for example 10 make him stop.

you will only have a problem with obstacles.

edit:
tell me if you need a code for this.

The vec_dist function does this for you.

Thanks all

@Fab4
I don't care about obstacles
well, a piece of code will be nice
thanks for your time

actually I want the camera to follow the player (something like Prince of Persia camera)
