Maxamor is correct. For both #1 and #2 you should not base anything on
frametime (unless you can atarget specific hardware and lock the framerate).

Use the stopwatch class in system.diagnostics to give you a time in seconds

Then do something like

if (gametime % 2.0 == 0)
show sprite

As far as animation goes, I recommend not making it based off of "x amount
of
frames display frame 0, x amount of frames display frame 1" etc...

The reason behind this is that each frame may not be the same amount of
time
depending on which computer your program is running on. This means the
animation may look great on your pc, but if it runs faster on someone
else's
the animation would go faster too, possibly too fast.

Make the animation time-based.

That way, each frame can have an amount of time that it displays itself
before it lets the next frame be drawn.

Then, you could just make a 2-frame animation for your flashing sprite.
One
is completely invisible, and the other is completely visible and have them
both display for 500ms or something. Then all you have to do is loop the
animation.

Hi

Any one now a good tutorial or can help me onhow to make a flashing
sprite.
I want to make a flashing arrow.

I have some ideas:

1) lower and increase the alpha levels per frame
2) have it non rendered and then rendered after x many frames..

My problem is for option 2...and 1 for that matter, how do i get it to
flash
at a pace i want?

Is this kind of solution mental? To make a class for the flashing sprite
that i call say SpriteFlasher.

Then in that class have a var for how many frames to allow to pass until
showing the sprite, and another var for howmany frames it should remain
visible for.

Then i could create an instance and pass in the frames passed on every
loop?
