Thanks Davemac, As soon as I posted that I realized my mistake! Silly error!! My brain said "as you're dealing with fractions of a second, you need to say "a = 0.6" as opposed to "a = 600". All good now though, thanks for your help. Paul.

Starting an action

Last reply by MLuedke, about 13 years ago:

Well, I wrote up everything and I'm pretty sure it'll work but the reference isn't working for some reason. I keep getting the error, "non-static method getY() cannot be referenced from a static context." I was just guessing at the reference for the actor, I know how to reference methods but not an actor or object.

When you want to start timing, set a field long startTime to be the current time: <Code Omitted> Then in your act method: <Code Omitted> Setting the startTime back to zero (and adding a check against zero to the if-condition) makes sure it will only trigger once when the time's up.

Memory leak?

Last reply by danpost, about 13 years ago:

It might make more sense using a 'switch' statement instead of all the 'if's, as follows: <Code Omitted>The '%' symbol means to get the remainder of what comes before it, divided by what comes after it. It is like saying i++; if (i == 6) { i = 0; }
