Trying to increase health bar when particle system drops hits the PImage. Not sure how to do it :/

The piece of code I am trying to get working is commented out in draw().

hb0.value == hb0.max Don't use == nor != in order to compare floating point values! [-X
In this case, use >= operator: hb0.value >= hb0.max

Ok thanks I changed that...Would u know how I could change my code so when a ball hits my image the health bar goes up?

GoToLoop

This is circle vs rectangle collision detection. I dunno that formula.
If precision isn't that important, you can consider your rectangle an ellipse or vice-versa. :D

AmyM

Yeah I do have a collision detection done with the ellipse but I cannot seem to figure out how to draw the increase of the health in the draw() function...I basically want the health to increase on screen when the function isDead() is activated.
