Hey :party:

I have a program that dynamically adds a child and removes a child 8 times every 700 ms. The size of the child changes each time. I also have a character that moves around while this is happening, an on Event listener. I have an FPS gauge and I am noticing FPS loss coming and going, but its not good that it comes at all :evil2:

The child is basically a line, and it is adding points or subtracting points, and then drawing that line. Would it be better for me just to add the 8 children, and rather than removing them and adding new ones, just append and subtract the new lines? Would that make this faster and not cause for an FPS loss?

ty!
