Chainsaw: Timer starts before countdown finishes #178

Closed rmmccann closed 10 years ago

I don't know if this really matters, but I noticed that the timer/fuel start as soon as the "start" button is pressed, but the logs cannot be cut until the countdown finishes.

Change needed to Chainsaw:

When the user clicks on Chainsaw's Start button, then stops before "Go" (and start of ability to cut), the fuel gage will not have moved, and DG will report FuelLeft as 40 and FuelLeftPercent as 100. The Fuel gage and countdown from 40 to 0 will start at Go, to give 40 (seconds) of cutting time, which is what we had before we added "Ready Set Go".

Hi Cliff,

Should we change Chainsaw so that is only uses fuel after the "Go" appears? At first I thought yes, but now I realize that it doesn't really matter, you can click start then stop right away, even before "Go". What we have done is make the game slightly harder since you can't cut until fuel has gone from 40 to 37, but it really doesn't make much difference. So I'd say keep it as is, why complicate things. I'd prefer it if the fuel didn't start until you could cut (at Go), esp if it isn't too hard to fix. Two reasons:

  1. It's already pretty hard to cut well in the time given, and we want fuel remaining so that it's clear that it needs to be worked into a score formula.
  2. Some kids have written formulas based on a rate (accepted pieces divided by time used), and if they blow three seconds up front, it would lead to a more complicated formula, assuming they thought about it.
