(8 directions) - how do I do to an enemy when he sees me in his radius of vision he chases me and attacks me
You could change the enemies angle towards the player and then activate the bullet behaviour to move towards him.
If you are familiar with installing plugins, I think the easiest way would be to install the 'MoveTo' behaviour by rexrainbow ( https://www.scirra.com/forum/behavior-moveto_t63156?&hilit=rex+moveto ) and simply let the enemy move to the player's location.
