java - Libgdx Texture Region is not flipping -
i had completed drawing texture region when trying flip texture region not working , isn't working when trying draw multiple frames. tried check velocity of body inside frame method gives me 0 when use code:
gdx.app.log(string.valueof(b2body.getlinearvelocity().x),"hi"); can me. code:
public class collector extends sprite { public enum state{standing,running,dead}; public state currentstate; public state previousstate; public world world; public body b2body; private textureregion collectorstand; private animation collectorrun; private float statetimer; private boolean runningright; public collector(world world,playscreen screen) { super(screen.getatlas().findregion("myboy1")); this.world=world; currentstate=state.standing; previousstate=state.standing; statetimer=0; runningright=true; array<textureregion> frames=new array<textureregion>(); for(int i=0;i<3;i++) frames.add(new textureregion(gettexture(),i*90,122,90,300)); //frames.add(new textureregion(gettexture(),90,122,110,300)); //frames.add(new textureregion(gettexture(),200,122,110,300)); collectorrun=new animation(0.1f,frames); frames.clear(); collectorstand=new textureregion(gettexture(), 0, 122, 89, 300); //collectorstand=new textureregion(gettexture(),90,122,110,300); //collectorstand=new textureregion(gettexture(),200,122,110,300); definecollector(); setbounds(0,0,50/fruits.ppm,100/fruits.ppm);//here can change size of our animation setregion(collectorstand); } public textureregion myregion(float dt) { textureregion region; region=collectorstand; gdx.app.log(string.valueof(b2body.getlinearvelocity().x),"hi"); if(b2body.getlinearvelocity().x<0 ) { region.flip(true,false); } return region; } public void update(float dt) { setposition(b2body.getposition().x - getwidth() / 2, b2body.getposition().y - getheight() / 2.8f); //setregion(myregion(dt)); setregion(getframe(dt)); } public textureregion getframe(float dt)// return appropriate frames sprite drawn { currentstate=getstate(); textureregion region; switch (currentstate) { case running: region=collectorrun.getkeyframe(statetimer,true); break; case standing: default: region=collectorstand; break; } gdx.app.log(string.valueof(b2body.getlinearvelocity().x),"hi"); if((b2body.getlinearvelocity().x<0 || !runningright)&& !region.isflipx()) { region.flip(true,false); runningright=false; } else if((b2body.getlinearvelocity().x>0 || runningright)&& region.isflipx()) { region.flip(true,false); runningright=true; } statetimer=currentstate==previousstate?statetimer+dt:0; previousstate=currentstate; return region; } public state getstate() { if(b2body.getlinearvelocity().x!=0) return state.running; else return state.standing; } public void definecollector() { bodydef bdef=new bodydef(); bdef.position.set(72/fruits.ppm,32/fruits.ppm); bdef.type=bodydef.bodytype.dynamicbody; b2body=world.createbody(bdef); fixturedef fdef=new fixturedef(); //polygonshape shape=new polygonshape(); circleshape shape=new circleshape(); shape.setradius(20/fruits.ppm); fdef.shape=shape; b2body.createfixture(fdef); } }
flipping using textureregion.flip() not approach constant flipping of images. time should doing when load image , being done once because computationally expensive since modifies image data flip rather draw flipped.
you should instead flip image when calling batch.draw(). here guide on how use batch calls more parameters: libgdx: rotate texture when drawing spritebatch i'm question poster :p
