Rolling a mob

Hello, can you help me with a mob in Mcreator 2024.4 for the Geckolib mob plugin ''vishap_fat", specifically its own attack. When it sees a player to attack, it first plays the ''roll_start'' animation, where it rolls into a ball before rolling. Then he makes a 10-block forward leap with a repeating animation of "roll", which stops when it reaches 10 blocks, and when it collides with the player, it deals 10 damage, and then the "roll_end" animation plays, where it unfolds after the roll and enters its natural state. It is important to note that the mob can only attack the player with this attack. Thank you in advance!
