I am trying to fire an action every 125ms.
To get the current milliseconds, I go this way:
double passedMs = GameTime.TotalGameTime.TotalMilliseconds; //this is a double as well currentMs += (currentMs - passedMs) if (currentMs > 125) { //Action currentMs = 0; } But the value I get in passedMs is not simply milliseconds, it's more like 8833.351.
So what could I do here?
My understanding is that TotalGameTime represents how long it's been since the executable opened. In your case, it's been up around 8 seconds. For your += statement, I think currently you're taking the difference of the two, and adding it to the current time...? I'm not even sure what that resulting value would be.
I think more likely, you're looking for ElapsedGameTime (documentation on MSDN); replace the contents of the parentheses with just that to get what you're looking for:
currentMs += GameTime.ElapsedGameTime.TotalMilliseconds; Also, I would advise you to subtract 125 from currentMs, rather than setting it to 0. If currentMS becomes 200, then it's going to have somewhat inconsistent timing.
if (currentMs > 125) { // Action currentMs -= 125; } Use an accumulation buffer, this way if you wait too long you don't waste the left-over. (But get your timing logic straight first)
currentMs += GameTime.ElapsedGameTime.TotalMilliseconds; if (currentMs > 125) { //Action currentMs -= 125; } EDIT: oh well other answer has got the same code now lol
