gritty sandal <@358291050957111296> Sorry bud for ping but can we talk ?

I guess

#

just join a VC

gritty sandal Jun 9, 2023, 2:46 PM

#

vital halo I guess

I cant speak english

#

:'[

vital halo Jun 9, 2023, 2:46 PM

#

oh ok

gritty sandal Jun 9, 2023, 2:50 PM

#

So as you know i am creating 54 cubes

And while doing rotation i will move them

So when i apply rotation 2 thing will happen cubes will get rotated on its own axis also from center, as you can see in video

So main problem i am getting is rotation on cubes own center

#

And i need to solve that

#

All cube changing their location rightly i just need to do something about center rotation

gritty sandal Jun 9, 2023, 2:52 PM

#

vital halo oh ok

I had one idea keeping track of all cubes location and its home location
(Here location means which side they belong either red,green,white etc)

And rotating it on its center according to this but i think its lengthy

#

You think there can be easy approch

vital halo Jun 9, 2023, 2:55 PM

#

Did you try using 0 0 0 as the pivot coordinates?

#

what happens when doing that?

gritty sandal Jun 9, 2023, 2:56 PM

#

vital halo Did you try using 0 0 0 as the pivot coordinates?

yep it have same results

#

goes to right cordinates but center rotation messed up

#

I need to deal with center rotation

I thought resizing a cube when it enter to another side would be good but i think that will also not work

vital halo Jun 9, 2023, 2:57 PM

#

and the problem also occurs on the first rotation?

gritty sandal Jun 9, 2023, 2:57 PM

#

vital halo and the problem also occurs on the first rotation?

Which?

#

First rotation no problem

#

For any side

vital halo Jun 9, 2023, 2:59 PM

#

How are you displaying the cube?

#

maybe try concatentating rotations?

gritty sandal Jun 9, 2023, 2:59 PM

#

vital halo How are you displaying the cube?

By adding cubes in a group class called cubeGroup

vital halo Jun 9, 2023, 3:00 PM

#

Can you show your cubeGroup?

gritty sandal Jun 9, 2023, 3:00 PM

#

And adding this class inside the scene

#

#

This one

#

I am just adding all cubes inside it

vital halo Jun 9, 2023, 3:01 PM

#

so you are transforming groups and not individual cubes?

gritty sandal Jun 9, 2023, 3:01 PM

#

And here it is added to scene

gritty sandal Jun 9, 2023, 3:01 PM

#

vital halo so you are transforming groups and not individual cubes?

I am rotating individual cubes

vital halo Jun 9, 2023, 3:01 PM

#

gritty sandal

but here, you add a transform to the whole group..?

gritty sandal Jun 9, 2023, 3:02 PM

#

vital halo but here, you add a transform to the whole group..?

Doing this so i can rotate the entire cube with mouse

#

its for this rotation

#

For rotation i am applying it to individual cubies

#

each of cube will rotate and transform

vital halo Jun 9, 2023, 3:05 PM

#

Can you try changing the rotation of a cube like that?

private Transform t=Rotate();
private box yourBox;
public void applyTransform(Transform toApply){
  t = t.createConcatenation(toApply);
  yourBox.getTransforms().clear();
  yourBox.getTransforms().add(t);
}

#

vital halo Can you try changing the rotation of a cube like that? ```java private Transform...

rotation of cube or side

gritty sandal Jun 9, 2023, 3:05 PM

#

gritty sandal its for this rotation

This one?

vital halo Jun 9, 2023, 3:06 PM

#

gritty sandal rotation of cube or side

add that code to the cube

#

and when rotating it, first create the rotate object

#

and then call yourCube.applyTransform(yourRotate)

#

and do the same thing for all other transforms on individual cubes

gritty sandal Jun 9, 2023, 3:08 PM

#

ok let me do it

#

I got it 50-60% but will give it try

vital halo Jun 9, 2023, 3:08 PM

#

not sure whether that makes a difference

vital halo Jun 9, 2023, 3:09 PM

#

gritty sandal its for this rotation

Does the problem still occur if you don't do that rotation?

gritty sandal Jun 9, 2023, 3:10 PM

#

vital halo Does the problem still occur if you don't do that rotation?

Obviously

gritty sandal Jun 9, 2023, 3:32 PM

#

vital halo Does the problem still occur if you don't do that rotation?

You there

vital halo Jun 9, 2023, 3:35 PM

#

Did xou try the thing with concatenations?

gritty sandal Jun 9, 2023, 3:36 PM

#

I just made class with it and try to apply that to individual cube

#

public class x{
private Transform t=new Rotate();
public void applyTransform(Transform toApply, Cube c){
t = t.createConcatenation(toApply);
c.m_B.getTransforms().clear();
c.m_B.getTransforms().add(t);
}
}

#

public void rotateFront(Cube[][][] c, String direction,x X) {//YELLOW
float a = .55f;
for(int i=0; i<6; i++) {
for(int j=0; j<3; j++) {
for(int k=0; k<3; k++) {
if(c[i][j][k].m_B.getTranslateZ() <= -150 || c[i][j][k].m_B.getTranslateZ() <= -100) {
Rotate rotate = new Rotate();
rotate.setAxis(rotate.Z_AXIS);
if (direction.equals("clockwise")) {
rotate.setAngle(a);
//r.setAngle(0.5);
} else if (direction.equals("counterclockwise")) {
rotate.setAngle(-a);
//r.setAngle(-90);
}
X.applyTransform(rotate, c[i][j][k]);
rotate.setAngle(5);
// Move the cube to its new position
double angle = Math.toRadians(rotate.getAngle());
double newX = c[i][j][k].m_B.getTranslateX() * Math.cos(angle) - c[i][j][k].m_B.getTranslateY() * Math.sin(angle);
double newY = c[i][j][k].m_B.getTranslateX() * Math.sin(angle) + c[i][j][k].m_B.getTranslateY() * Math.cos(angle); c[i][j][k].m_B.setTranslateX(newX);
c[i][j][k].m_B.setTranslateX(newX);
c[i][j][k].m_B.setTranslateY(newY);
}
}
}
}

vital halo Can you try changing the rotation of a cube like that? ```java private Transform...

How to do this editor

vital halo Jun 9, 2023, 3:37 PM

#

No, I meant this as an instance method of your cube class

gritty sandal Jun 9, 2023, 3:37 PM

#

vital halo No, I meant this as an instance method of your cube class

Oh ok

gritty sandal Jun 9, 2023, 3:37 PM

#

vital halo No, I meant this as an instance method of your cube class

But still there is one problem budd

vital halo Jun 9, 2023, 3:38 PM

#

and why do you change the translate manually?

#

shouldn't the rotate do that?

gritty sandal Jun 9, 2023, 3:39 PM

#

vital halo and why do you change the translate manually?

Where

#

double angle = Math.toRadians(rotate.getAngle());
double newX = c[i][j][k].m_B.getTranslateX() * Math.cos(angle) - c[i][j][k].m_B.getTranslateY() * Math.sin(angle);
double newY = c[i][j][k].m_B.getTranslateX() * Math.sin(angle) + c[i][j][k].m_B.getTranslateY() * Math.cos(angle); c[i][j][k].m_B.setTranslateX(newX);
c[i][j][k].m_B.setTranslateX(newX);
c[i][j][k].m_B.setTranslateY(newY);

THis?

vital halo Jun 9, 2023, 3:40 PM

gritty sandal public void rotateFront(Cube[][][] c, String direction,x X) {//YELLOW ...

at the end of that

gritty sandal Jun 9, 2023, 3:41 PM

#

vital halo at the end of that

My cubes will rotate on position

#

i need to move them in the forward to create rotation

vital halo Jun 9, 2023, 3:42 PM

#

oh I thought Rotate is doing both of these things

#

can you use a Translate object instead of doing the translation manually maybe?

gritty sandal Jun 9, 2023, 3:56 PM

#

vital halo can you use a `Translate` object instead of doing the translation manually maybe...

But it will be same tbh

#

Nothing will be changed

vital halo Jun 9, 2023, 3:58 PM

#

Is it? Or would old rotations be applied to the new positions?

gritty sandal Jun 9, 2023, 4:05 PM

#

vital halo Is it? Or would old rotations be applied to the new positions?

Nothing is working

#

-_-

#

or i am applying it wrong way

#

I am so frustrated man

#

pepehands

vital halo Jun 9, 2023, 4:06 PM

#

what ate you doing?

gritty sandal Jun 9, 2023, 4:06 PM

#

vital halo what ate you doing?

You said apply that function rotation applied that

#

public void rotateFront(Cube[][][] c, String direction) {//YELLOW
float a = 90f;
for(int i=0; i<6; i++) {
for(int j=0; j<3; j++) {
for(int k=0; k<3; k++) {
if(c[i][j][k].m_B.getTranslateZ() <= -150 || c[i][j][k].m_B.getTranslateZ() <= -100) {
Rotate rotate = new Rotate();
rotate.setAxis(rotate.Z_AXIS);
if (direction.equals("clockwise")) {
rotate.setAngle(a);
//r.setAngle(0.5);
} else if (direction.equals("counterclockwise")) {
rotate.setAngle(-a);
//r.setAngle(-90);
}
c[i][j][k].applyTransform(rotate);

// Move the cube to its new position
double angle = Math.toRadians(rotate.getAngle());
double newX = c[i][j][k].m_B.getTranslateX() * Math.cos(angle) - c[i][j][k].m_B.getTranslateY() * Math.sin(angle);
double newY = c[i][j][k].m_B.getTranslateX() * Math.sin(angle) + c[i][j][k].m_B.getTranslateY() * Math.cos(angle); c[i][j][k].m_B.setTranslateX(newX);
c[i][j][k].m_B.setTranslateX(newX);
c[i][j][k].m_B.setTranslateY(newY);
}
}
}
}

#

Btw how to send code in that window

vital halo Jun 9, 2023, 4:07 PM

#

I thibk manually applying the translations with setTranslateX instead of using a Translate object could be the cause of the issue

#

but I am not experienced with JavaFX 3D stuff

#

or any 3D stuff

gritty sandal Jun 9, 2023, 4:08 PM

#

vital halo or any 3D stuff

Atlest you helpin man thats great thing , I am great someone is helping me :]

#

All other server are dead

#

-_-

vital halo Jun 9, 2023, 4:09 PM

#

Can you try creating a Translate object?

#

for the translations

vital halo Jun 9, 2023, 4:09 PM

#

gritty sandal All other server are dead

not really

gritty sandal Jun 9, 2023, 4:23 PM

#

vital halo not really

Me closing this post

I will apply that approch keeping track of all side and add rotation according to it

#

Have a great day

#

And take care because i need more help in future 😛

vital halo Jun 9, 2023, 4:24 PM

#

btw you don't need to lose the post before you solve your problem

gritty sandal Jun 9, 2023, 4:24 PM

#

vital halo btw you don't need to lose the post before you solve your problem

Oh i thought it will automatically close

#

So i close whenever i go offline

vital halo Jun 9, 2023, 4:24 PM

#

it gets dormanted

#

after 300 minutes, it will be marked as dormant

#

but you cab reopen it by sending a message in that post

gritty sandal Jun 9, 2023, 4:25 PM

#

I see then I will keep it as it is

#

Byw
