PlayerAttack

[nickmattinson]

• [ ] for the basic player attack, I want a small circle to follow the mouse pointer around, if the pointer is within the range of the basic attack, the circle glows green, if the pointer is too far, then the circle glows orange. The player can still attack in that direction but the attack will only reach max distance. The attack will spawn a line (of electricity) from the player to the mouse pointer. slight AOE because I want to give the player a little breathing room (very small circle).

• [x] I want hitpoints to spawn above the enemy with how much damage the player dealt. red font and rises above the enemy's last position and fades out.

• [ ] the advanced attack is a right click AOE attack that deals damage within a larger circle, can be anywhere on the screen.
