Int round

[hosdank]

I'm programming a simple app that has a circle in it. You can select the circle with the cursor and move it around(Or so I'm hoping to achieve one day :P). To handle a gradual acceleration PART of my code is:


function accelerate(velvar:int, maxspeed:int):int
{
if( velvar < maxspeed )
{
if(!brakes)
{
velvar += 0.5;
}
}
trace(velvar);
return velvar;
}


then later I have:

velocity = accelerate(velocity, 5);
mycirc.x += velocity;
(mycirc being the sprite)

The weird thing is that velocity never gets over 1. :P If you need anymore code from my program I'll be happy to post it. Thanks :)

What is brakes referring to? How and when is it set?

Try placing a trace within the !brakes condition and see if it's being run.

I'm assuming that you're feeding the function a value for maxspeed that's greater than 1. Is that correct? What are you feeding for the velvar value?

My guess is the trouble is with the !brakes condition. If it's true, it should be throwing an error. If there is no error, my guess is that it's not being run. You might try replacing it with if(brakes == "") or something similar.

Brakes is a boolean value that decides if the ship should start to slow down(Basically if the it get within its (destination point - velocity))
I'll try out what you said. Thanks :)

Yeah, it is getting in the if :(

How are you running the function?

Your logic and coding are fine. I didn't take a very through look at it, but I don't see any glaring errors.

Try adding a trace to the beginning of the function and make sure the values are what you expect them to be.

Which function?
