#
Hello everyone, im trying to create a game for class and im having a couple of problems. for example i cannot seem to figure out how to animate directional idle animations and shooting animations. Having a idle animation in one direction was simple enough since i only animated one direction. However i dont know how to tell the programm in what direction i have previously used as in to give my game information what idle or standing shooting animation to use. Next Problem is, if i want to create an improved jump i am facing two problems. First, i do not know how to program a jump in which i can control the high of so to give it that megaman feel. Second, nor do i know if i am able to create such a jump how to tell the game to play a different animation after the apex of the jump and when landing rather then after some unchangable time . The following is the entire code of my Character. It would be really nice if somebody could help me. I know there are probably already threats about these problems but despite my hardest effort i was not able to understand them.
?

To change jump height, just add or subtract a small value (maybe up to 10) when applying jumpstrength to vSpeed. Maybe adding a parameter to the jump method would help, to pass the jump strength to it:
?
1
2
3
4
5
6
private void jump(int strength)
{
    vSpeed = -strength; // strength should be set to vSpeed, not just subtracted from its value
    jumping = true;
    fall();
}
Then a normal jump would be coded:
?
1
jump(jumpStrength);
and a small jump might be:
?
1
jump(jumpStrength-10);
For better control on your animations, you might consider placing each animation image set in a separate array. Then you can add a field to indicate which array of images is currently in use. You could also add a field to indicate which animation set is "pending" to be used next.

Uh yes that entire last part, could you explain that a little more as in what exactly would i have to write? I am a Novice at this so im sorry for the troubles. I am yet not able to make up my own code, i can only look up whats been done before.

By placing the images of your animation sets into arrays:
?
1
2
3
4
5
6
7
8
private static GreenfootImage[] standAnim = new GreenfootImage[9];
private static GreenfootImage[] rightAnim; = new GreenfootImage[11];
 
static
{
    for (int i=0; i<standAnim.length; i++) standAnim[i] = new GreenfootImage("Stand_0"+(i+1)+".png");
    for (int i=0; i<rightAnim.length; i++) rightAnim[i] = new GreenfootImage("Walk-A_"+(i < 10 ? "0" : "")+(i+1)+".png");
}
they will be organized in groups. The 'static' modifier makes the members (fields declared in lines 1 and 2) class members, as opposed to instance members, allowing the arrays to be set up at compile time instead of during run time. This is allowed, as all instances of the class can use the same image sets. Next, you can add an instance field to indicate which image set is currently being used by an actor of the class:
?
1
private GreenfootImage[] animSet = standAnim;
Initially setting it to the standing image set makes sense as no key states are evaluated until the act method is executed on the actor. Finally, running the current animation needs to be done with a little care as the animation sets are not all of equal length. Also, your frame and animationCounter fields can be combined into one counter (animCount). However, because they do not all have equal frame rates, you will need another field for its value and it must be adjusted any time you change the current animation set:
?
1
2
3
4
5
6
7
8
9
10
11
12
// with the following fields
private int animCount; // counter for animations
private int animDelay = 6; // initially set for standing animation (frame rate field)
 
// this method might help
private void setAnim(GreenfootImage[] anim, int frameRate)
{
    animSet = anim;
    animCount = -1; // prepares to set first image when incremented
    animDelay = frameRate;
    animate(); // calls a method to set a frame of this newly set animation
}
The animate method can be written as follows:
?
1
2
3
4
5
private void animate()
{
    animCount = (animCount+1)%(animSet.length*animDelay);
    if (animCount%animDelay == 0) setImage(animSet[animCount/animDelay];
}
That is it. You can dispense with your animateStand and animateWalkA codes.

Sidenote: I was never much a fan of "if (onGround()) { ... } else fall();" code. This is akin to saying gravity does not exist unless you are up in the air. I prefer:
?
1
2
3
4
5
6
7
8
9
10
11
12
boolean onGround = false; // assume in air
vSpeed += acceleration; // apply gravity
setLocation(getX(), getY()+vSpeed); // fall
Actor actor = getOneIntersectingObject(Actor.class);
if (actor != null)
{ // colliding with another actor
    int vDir = (int)Math.signum(vSpeed); // vertical direction of movement
    vSpeed = 0; // kill vertical speed
    if (vDir > 0) onGround = true; // landing and not bopping head
    setLocation(getX(), actor.getY()-vDir*(actor.getImage().getHeight()+getImage().getHeight())/2); // assigning stop location
}
if (onGround && Greenfoot.isKeyDown("space")) vSpeed = -20; // initiate a jump
This does pretty much everything for vertical movement (initiating a jump, falling and colliding with other actors).

I really appreciate the effort but i have to say this is all a little complicated for me. All that code, i dont understand from where its coming. When i copy it i also get errors so i dont know what to do. I tried using a Counter for a work around as following.
?
1
2
3
4
5
6
7
8
9
public void Counter()
    {
         
        if(Greenfoot.isKeyDown("right"))
        Counter = 0;
         
        if(Greenfoot.isKeyDown("left"))
        Counter = 1;
    }

public void animationCheckRight()
    {
         
         
        if(Greenfoot.isKeyDown("right") && canMoveRight() )
        {
            if(animationCounter % 4 == 0){
                animateWalkA();
                 
            }
            }
            else
            {
                if(animationCounter % 6 == 0 && Counter==0){
                 animateStand();
                  
                }
            }
         
         
    }
     
    public void animationCheckLeft()
    {
         
         
         
        if(Greenfoot.isKeyDown("left") && canMoveRight() )
        {
            if(animationCounter % 4 == 0){
                animateWalkLeftA();
                 
            }
        }
    }
And this seems to work i think, as in when i press left he does the proper animation. However now i have the problem after a couple of seconds if i stop running there is like a 50% chance that the animation breaks. This happens regartless of where i have the animation. It doesnt matter if i have it in move, act or in its own thing. Do you maybe a have a idea on why that happens?

I really have a hard time understanding what youre writing, is there maybe an easier way for the programm to not keep on breaking the animation or like telling it to restart?

You can ask about any specific part of it for clarification (one part at a time).
When i copy it i also get errors so i dont know what to do. I tried using a Counter for a work around as following. << Codes Omitted >> And this seems to work i think, as in when i press left he does the proper animation. However now i have the problem after a couple of seconds if i stop running there is like a 50% chance that the animation breaks. This happens regartless of where i have the animation. It doesnt matter if i have it in move, act or in its own thing. Do you maybe a have a idea on why that happens?
You should not need a counter. Please show the current class codes (in its entirety). Also, if you are getting errors on it, copy/paste them here so we can better understand what might be going on.

This is the entire code. Im getting errors at: private static GreenfootImage rightAnim; = new GreenfootImage; But that is Probably because there is a ; to many. Then in the same line im getting errors at the . However if i remove the ; after rightAnim im getting errors at all these lines: private void setAnim(GreenfootImage anim, int frameRate) { animSet = anim; animCount = -1; // prepares to set first image when incremented animDelay = frameRate; animate(); // calls a method to set a frame of this newly set animation } // with the following fields private int animCount; // counter for animations private int animDelay = 6; // initially set for standing animation (frame rate field) // this method might help private void setAnim(GreenfootImage anim, int frameRate) { animSet = anim; animCount = -1; // prepares to set first image when incremented animDelay = frameRate; animate(); // calls a method to set a frame of this newly set animation }

Im getting errors at: private static GreenfootImage rightAnim; = new GreenfootImage; But that is Probably because there is a ; to many.
Correct. The first one on that line should be removed.
However if i remove the ; after rightAnim im getting errors at all these lines: << Code Omitted >>
Not sure as to why that would be. Although, you are missing the animate method I provided which is called from the setAnim method.

I see. However, you have not removed any of the lines that was to be replaced with the codes I provided, which was pretty much ALL your previously given animation codes. Your added animations should be done similar to what I provided, as well.

Im sorry i dont think i understand where to put all of this and what do with the errors. Im currently trying to add the gravity part you added and the animations but i dont know what parts need to be removed. I know this is asking for a lot but could you maybe give me the whole code of how you want it to be. As in to show me what needs to be where and what needs to be removed so i can use that as reference ?

Using the code that you originally gave (in your first posting), the parts being replaced (and that would need to be removed) are as follows: * lines 19 through 39 (replaced by static content) * line 42 (replaced by animCount) * lines 104 through 111 (to be replaced later) * lines 251 through 359 (replaced with animate method I provided, which you as yet have not added) The animate method will also need to be called from somewhere in the act method.
