Question

Hello I have the actionscript code here for a bubble popping game. When the game starts, bubbles fall down from the top of the game to the bottom and score is kept for the most bubbles clicked or popped in 30 seconds.

The size of the bubble is defined by the initialize method in the code, and uses ToString() to calculate the score. ToString gives me a 1061: Call to a possibly undefined method Random through a reference with static type uint. This error which I cannot figure out where it comes from.

If anyone with experience in AS3 could give me some pointers to my faults, I would greatly appreciate it. Thank You.

You need to change each occurrence of

Math.Random()

to

Math.random()

note the lowercase r

Or…since it looks like you just edited this question for ToString()

Try

toString()

Notice how similar the errors are. You’re tying to call a method that doesn’t exist on both of these. Capitalization matters VAR is not the same as var
