So I was wondering if there was a way to make a variable raise at lets say + 1 ever .5 seconds... I'm still a slight beginner, and never got into the very specialty things when i was learning plain Java...
Thanks in advnace.

Making a variable raise at a slower rate
You could use seconds, but it's easier just to use act cycles instead which is what you want most of the time. The usual approach is to increment a counter on every iteration of act - you could do this, and when the counter say reached 20 (fiddle with this number to get the effect you want) set the counter back to 0 and increment the variable you want to increment every few seconds.
how do you increment a counter?
my problem is that I have one image, and I want to change that to another image every 3 seconds, then change it back to the first image and carry on doing that. how do I do that?
I'd explain now but I've got something to do (I'll try to remember to explain later).
Also how long do you want the second image to be up for?
each image should be up for like 2 seconds then change so my image doesnt look like it has a hyperactive disorder :D
@faizakamal
You want an Actor to change its image every couple of seconds? Here's a suggestion:
Change what frameNum has to equal to adjust the time between image changes. You can add as many frames to the animation a you want.
public class Actor {
//...(your normal instance variables)
//add this after your normal variables.
private int frameNum;
//...(methods)
public void act()
{
//...do whatever you want it to do....
//...but make sure to add animate()
animate();
}
//This is where you will animate the Actor.
private void animate()
{
if(frameNum == 0) {setImage(whateverImageYouUse);}
else if(frameNum == 20) {setImage(whateverImageYouUse2);}
//...and so on, until you get to the last image:
else if(frameNum == 40) {
setImage(lastImageYouUse);
frameNum = 0;
}
//this is where you update the frameNum
frame++;
}
}
@Morran, that was a really good reply, seeing as it was very clear :) Its good that you've joined the community
private void animate()
{
if(frameNum == 0)
{
setImage(image1);
}
else if(frameNum == 20)
{
setImage(image2);
}
else if(frameNum == 39)
{
setImage(image1);
frameNum = 0;
}
frame ++;
}
}
Date dt= new Date();
Long time= dt.getTime();//this is the ms(1000ms = 1s) number beginfrom 1970_1_1_00:00:00_0ms
I didn't try it, but if ti's OK.I think it would help.
