Hello,

I'm writing a program in Visual C++ Express with Dark GDK. The game uses the arrow keys to control the speed of a ball that bounces around arkanoid-style. I have a problem, though. If I hold down an arrow key, the ball goes faster and faster and faster. Is there a way to ignore the fact that the key is held down and just increment my counter once, regardless of how long the key is held? Here's the bit of code that's giving me grief:



Thanks!

You can download my InputState class to easily do this:

Thanks, Bran, but this program is for a class, so it has to work when I send it to my professor. Any ideas?

Could you just limit it with an if statement?

For example:


I may not be understanding what you actually want to do though!

do this:



declare the Rightkeytimer as an int, "int Rightkeytimer;" before void DarkGDK ()
and do the same for the other variables... obiously with their respective names.

what this code does is that it checks to see if right is being pressed. if it is pressed, then check if the timer is 0, if so, add 1 to movex and 1 to the timer... so next time it tries to enter to add 1 to movex it wont since the timer is 1 then 2 then 3 and so on... and, the most important part is resetting the timer if the key is not being held, that is done in the else. if the key is not being press the timer is 0.



Hope it helps it will work


OR you could in fact, use Bran flakes91093 inputstate class which is very handy.

there can be several points for the if statement that make the object appeir to slow down. I am assuming that you are tring to make a 3rd person object slow down on a slope this is also a problem I had. The problem lies when the player gets closer and closer to a slope. It will decress speed as the slope increases.

Go through yourself at a wall.

Thanks for your advice, everyone. I asked my professor and he told me to just put an empty while loop inside of my if statement, like so:



Simple, elegant, functional.

Thanks again!

lol i just made that and what this does it loops indefinetly... youd better use my example or another method, i think what your proffesor made you do is simple, it may look elegant, but it does not function at all with all given respect!

I didn't think it looked right, because the while-loop is being terminated right after it's called. Are you sure this is the correct snippet, Rob?

Change the ; after your while statement to { } like so:



Oh and I don't think the != 0 is really needed...

if(enemy == Amnzero) runAway();
