This is the create() Method:
batch = new SpriteBatch();
texture = new Texture(Gdx.files.internal("spaceships/tfighter0.png"));
sprite = new Sprite(texture);
sprite.setOrigin(sprite.getWidth()/2, sprite.getHeight()/2);
sprite.rotate(180f);
And the render() Method:
Gdx.gl.glClearColor(0, 0, 0, 0);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
batch.draw(sprite ,200,200);
batch.end();
Shouldn't the sprite be rotated now? It just looks the same as the png no matter what degree I put into the rotate method.
Using
sprite.draw(batch)
Instead of
batch.draw(sprite,x,y)
works

I need to set the Sprite(Hello) position to stay with the mesh...Now, the Sprite is independent. If I rotate the object, the Sprite should stay with the mesh
LATER EDIT:
Mesh position is always 0..
I tried for couple of hours but nothing worked..
Here is a screenshot of the code:
And the code...
loader.load('/3D_Cars/Dacia_1410_Tuned/components/scene.gltf', function (gltf) {
carModel = gltf.scene.children[0];
gltf.scene.traverse(function (child) {
if (child.isMesh) {
var v = new THREE.Vector3(0, 0, 0);
domEvents.addEventListener(carModel.getObjectByName(child.name), 'click', function (event) {
app.RenameAsCarParts(child.name)
console.log(child.name)
}, false)
if (child.name == 'rim_RSL1_Aluminium_0') {
child.position.set(100, 50, 3); //testing
var spritey = makeTextSpriteNew(" Hello ",
{ fontsize: 15, textColor: { r: 0, g: 0, b: 0, a: 1.0 } });
scene.add(spritey);
}
}
});
carModel.getObjectByName('Body_paint_0').material = bodyMaterial;
carModel.rotation.set(Math.PI / 2, 0, 0);
carModel.rotateY(Math.PI);
scene.add(carModel);
});
Thank you!
Where is this method defined makeTextSpriteNew?
You can refer this three.js example for drawing Text Sprites in three.js
https://stemkoski.github.io/Three.js/Sprite-Text-Labels.html
The idea is, you need to provide a 3d position to this sprite so that it will project that position on screen and display the Sprite.
In your case you need to provide it the mesh's position (bounding box corner/center based on where you need to show the sprite).
spritey.position.set(posX, posY, posZ);
Im trying to make a isometric videogame in Libgdx and when Im programming the animations I have a strange error.
I have two 3 tiles in the scene: static body without animation, tile floor and body with animation.
All have the same coordinates and the static body wihout animation and tile floor are in the same position but the body with animation are in wrong position.
Here a image, all in the image are in the same scene at the same time:
Image from scene
Static body is a frame from Spritesheet of the animation.
Here is my relevant code:
TextureAtlas texureAtlasHair;
Animation<TextureRegion> animationHairHeroRunning;
SpriteBatch batch;
texureAtlasHair = new TextureAtlas("hero/ClothesBueno/ClothesB.atlas");
animationHairHeroRunning = new Animation<TextureRegion>(1f/4f,texureAtlasHair.findRegions("Stance"));
heroLoad = new Texture("map/Stance_1.png");
heroLoadSprite = new Sprite(heroLoad);
heroLoadSprite.flip(false,true);
public void render() {
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.setProjectionMatrix(dungeonCam.combined);
dungeonCam.update();
batch.begin();
elapsedTime += Gdx.graphics.getDeltaTime();
//FloorTile
Vector2 pointFloor = twoDToIso(new Vector2(25,30));
batch.draw(floor,pointFloor.x,pointFloor.y);
//Hero without animation
Vector2 pointHero = twoDToIso(new Vector2(25,30));
batch.draw(heroLoadSprite,pointHero.x,pointHero.y);
//Hero with animation
TextureRegion currentFrameHair =
animationHairHeroRunning.getKeyFrame(elapsedTime,true);
batch.draw(currentFrameHair,pointHero.x,pointHero.y,128,-128);
batch.end();
}
public Vector2 twoDToIso(Vector2 punto) {
Vector2 tempP = new Vector2(0, 0);
tempP.x = (punto.x - punto.y) * 32;
tempP.y = (punto.x + punto.y) * 16;
return tempP;
}
Edit
AtlasImage
And my .atlas is like this.
.atlas
And my actual code to AtlasRegions:
Array<TextureAtlas.AtlasRegion> arrayRegions;
texureAtlasHair = new TextureAtlas("hero/ClothesBueno/ClothesB.atlas");
arrayRegions = texureAtlasHair.findRegions("Stance");
animationHairHeroRunning = new Animation(1f/4f,arrayRegions);
In p5.js resizeCanvas(x, y) is a function for p5 objects but if I made a p5.Graphics object, can I resize it with a similar function?
Interestingly, p5.Graphics objects can run resizeGraphics() but nothing happens (including no error) and the height and width remain the same in the console.
g = createGraphics(50, 50); //creates p5.Graphics
g.resizeCanvas(100, 100); //fails: silently without error
g.resize(100, 100); //fails: resize has not been defined
Is there another function or would I need to actually extract the cooresponding graphics canvas and call a native javascript function instead?
Thanks!
If you want to resize a P5.Graphics, you can just create a new one, then draw the old one to the new one.
Here is an example:
var pg;
function setup() {
createCanvas(1000, 1000);
pg = createGraphics(100, 100);
pg.background(100);
pg.noStroke();
pg.ellipse(pg.width/2, pg.height/2, pg.width, pg.height);
}
function draw() {
background(200);
image(pg, 0, 0);
}
function mouseClicked(){
var newPG = createGraphics(mouseX, mouseY);
newPG.image(pg, 0, 0, newPG.width, newPG.height);
pg = newPG;
}
Using resizeCanvas on a graphics object created with "createGraphics" seems to stretch the graphics rather than resize the buffer.
Right now the best way to resize a graphics object is to simply set the width and height properties directly.
// Some graphics object
let graphics = createGraphics(w,h);
// Now simply resize like this
graphics.width = gWidth;
graphics.height = gHeight;
As suggested here:

I want to update the position of my sprite. But it is moving downwards then jumps a little and then stops. It doesn't even move left or right. I want it to move left, right, up and down based on tilt.
Here is my code:-
Scene scene = new Scene();
scene.setBackground(new Background(1.09804f, 0.6f, 3.0f));
playerSprite = new AnimatedSprite(10, 10, 48, 64, pTextureRegion, getVertexBufferObjectManager());
playerSprite.animate(300);
PhysicsWorld physicsWorld = new PhysicsWorld(new Vector2( 0, SensorManager.GRAVITY_MOON), false);
FixtureDef PLAYER_FIX = PhysicsFactory.createFixtureDef(10.0f, 0.5f, 0.0f);
Body playerBody = PhysicsFactory.createBoxBody(physicsWorld, playerSprite, BodyType.DynamicBody, PLAYER_FIX);
physicsWorld.registerPhysicsConnector(new PhysicsConnector(playerSprite, playerBody, true, false));
scene.attachChild(playerSprite);
In your
PhysicsWorld physicsWorld = new PhysicsWorld(new Vector2( 0, SensorManager.GRAVITY_MOON), false);
Change SensorManager.Gravity_Moon which makes a constant gravity pull directed down for all your objects - to .Sensor_Orientation. Im not sure which one exactly you have to choose but there is your problem. Try some other .Sensor_xxx if the one I told you doesn't work.
public void onAccelerationChanged(AccelerationData pAccelerationData) {
// TODO Aiuto-generated method stub
Vector2 gravity = Vector2Pool.obtain(pAccelerationData.getX(), pAccelerationData.getY());
this.physicsWorld.setGravity(gravity);;
Vector2Pool.recycle(gravity);
I am trying to figure out a way to cut out a certain region of a background texture such that a certain custom pattern is not rendered on the screen for that background. For example:
This square can be any pattern.
I am using Frame Buffer Object and Stencil Buffer to achieve this kind of effect. Here is the code:
fbo.begin();
//Disables ColorMask and DepthMask so that all the rendering is done on the Stencil Buffer
Gdx.gl20.glColorMask(false, false, false, false);
Gdx.gl20.glDepthMask(false);
Gdx.gl20.glEnable(GL20.GL_STENCIL_TEST);
Gdx.gl20.glStencilFunc(GL20.GL_ALWAYS, 1, 0xFFFFFFFF);
Gdx.gl20.glStencilOp(GL20.GL_REPLACE, GL20.GL_REPLACE, GL20.GL_REPLACE);
stage.getSpriteBatch().begin();
rHeart.draw(stage.getSpriteBatch(), 1); //Draws the required pattern on the stencil buffer
//Enables the ColorMask and DepthMask to resume normal rendering
Gdx.gl20.glColorMask(true, true, true, true);
Gdx.gl20.glDepthMask(true);
Gdx.gl20.glStencilFunc(GL20.GL_EQUAL, 1, 0xFFFFFFFF);
Gdx.gl20.glStencilOp(GL20.GL_KEEP, GL20.GL_KEEP, GL20.GL_KEEP);
background.draw(stage.getSpriteBatch(), 1); //Draws the background such that the background is not rendered on the required pattern, leaving that area black.
stage.getSpriteBatch().end();
Gdx.gl20.glDisable(GL20.GL_STENCIL_TEST);
fbo.end();
However this is not working at all. How am I supposed to do this using Stencil Buffers? I am also facing some difficulty understanding glStencilFunc and glStencilOp. It would be very helpful if anyone can shed some light on these two.
UPDATE: I have also tried producing something of the same kind using glColorMask. Here is the code:
Gdx.gl20.glClearColor(0, 0, 0, 0);
stage.draw();
FrameBuffer.clearAllFrameBuffers(Gdx.app);
fbo1.begin();
Gdx.gl20.glClearColor(0, 0, 0, 0);
batch.begin();
rubber.draw(batch, 1);
Gdx.gl20.glColorMask(false, false, false, true);
coverHeart.draw(batch, 1);
Gdx.gl20.glColorMask(true, true, true, false);
batch.end();
fbo1.end();
toDrawHeart = new Image(new TextureRegion(fbo1.getColorBufferTexture()));
batch.begin();
toDrawHeart.draw(batch, 1);
batch.end();
This code is producing this:
Instead of something like this: (Ignore the windows sizes and colour tones)
Note: I am using the libgdx library.
While drawing to a SpriteBatch, state changes are ignored, until end() is called. If you want to use stenciling with SpriteBatch, you'll need to break up the batch drawing. One thing, I've left out FBOs, but that shouldn't make a difference.
#Override
public void create() {
camera = new OrthographicCamera(1, 1);
batch = new SpriteBatch();
texture = new Texture(Gdx.files.internal("data/badlogic.jpg"));
texture.setFilter(TextureFilter.Linear, TextureFilter.Linear);
TextureRegion region = new TextureRegion(texture, 0, 0, 256, 256);
sprite = new Sprite(region);
sprite.setSize(1f, 1f);
sprite.setPosition(-0.5f, -0.5f);
spriteUpsideDown = new Sprite(new TextureRegion(texture, 1f, 1f, 0f, 0f));
spriteUpsideDown.setSize(1f, 1f);
spriteUpsideDown.setPosition(-0.5f, -0.5f);
pattern = new Sprite(region);
pattern.setSize(0.5f, 0.5f);
pattern.setPosition(-0.25f, -0.25f);
<< Set Input Processor >>
}
The input processor allows to set two boolean flags breakBatch1 and breakBatch2 via keyboard (libgdx on desktop), which are used to break the SpriteBatch drawing.
#Override
public void render() {
Gdx.gl.glClearColor(1, 1, 1, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_STENCIL_BUFFER_BIT);
batch.setProjectionMatrix(camera.combined);
// setup drawing to stencil buffer
Gdx.gl20.glEnable(GL20.GL_STENCIL_TEST);
Gdx.gl20.glStencilFunc(GL20.GL_ALWAYS, 0x1, 0xffffffff);
Gdx.gl20.glStencilOp(GL20.GL_REPLACE, GL20.GL_REPLACE, GL20.GL_REPLACE);
Gdx.gl20.glColorMask(false, false, false, false);
// draw base pattern
batch.begin();
pattern.draw(batch);
if(breakBatch1) { batch.end(); batch.begin(); }
// fix stencil buffer, enable color buffer
Gdx.gl20.glColorMask(true, true, true, true);
Gdx.gl20.glStencilOp(GL20.GL_KEEP, GL20.GL_KEEP, GL20.GL_KEEP);
// draw where pattern has NOT been drawn
Gdx.gl20.glStencilFunc(GL20.GL_NOTEQUAL, 0x1, 0xff);
sprite.draw(batch);
if(breakBatch2) { batch.end(); batch.begin(); }
// draw where pattern HAS been drawn.
Gdx.gl20.glStencilFunc(GL20.GL_EQUAL, 0x1, 0xff);
spriteUpsideDown.draw(batch);
batch.end();
}
Gdx.gl20.glStencilFunc(GL20.GL_REPLACE, GL20.GL_REPLACE, GL20.GL_REPLACE);
These are not the right arguments to glStencilFunc. I think you mean glStencilOp here.
You need to use glGetError in your code, it will alert you to these kinds of errors.
I believe your problem is that your initial GL_REPLACE stencil operation is applied to all the drawn pixels by your rHeart.draw regardless of the shape of any texture applied on the quad.
Thus, the stencil value is applied to every pixel of your quads which gives your problem.
If the texture applied on your quad has an alpha channel, as GL_ALPHA_TEST is not supported, you could setup your shader to discard the totally transparent pixels, preventting them from being drawn to the stencil buffer.
