Hi, this is the code that i'm using:
#include <osg/Node>
#include <osg/MatrixTransform>
#include <osg/Group>
#include <osg/Timer>
#include <osgGA/TrackBallManipulator>
#include <osgDB/ReadFile>
#include <osgDB/WriteFile>
#include <osgViewer/Viewer>
#include <iostream>
#include <osgViewer/ViewerEventHandlers>
#include <osgAnimation/BasicAnimationManager>
using namespace std;
static osg::Timer_t old_tick,new_tick;
int bandera=0;
static double delta;
class tankControll: public osgGA::GUIEventHandler{
public:
tankControll(){
acc=0;
};
virtual bool handle(const osgGA::GUIEventAdapter&
ea,osgGA::GUIActionAdapter& aa){
if(ea.getEventType()==osgGA::GUIEventAdapter::KEYDOWN &&
(ea.getKey()=='q' || ea.getKey()=='Q')){
bandera=0;
bandera=1;
return true;
}else if(ea.getEventType()==osgGA::GUIEventAdapter::KEYDOWN &&
(ea.getKey()=='w' || ea.getKey()=='W')){
bandera=0;
bandera=2;
return true;
}else if(ea.getEventType()==osgGA::GUIEventAdapter::KEYDOWN &&
(ea.getKey()=='e' || ea.getKey()=='E')){
bandera=0;
bandera=3;
return true;
}else if(ea.getEventType()==osgGA::GUIEventAdapter::KEYDOWN &&
(ea.getKey()=='a' || ea.getKey()=='A')){
bandera=0;
bandera=4;
return true;
}else if(ea.getEventType()==osgGA::GUIEventAdapter::KEYDOWN &&
(ea.getKey()=='s' || ea.getKey()=='S')){
bandera=0;
bandera=5;
return true;
}else if(ea.getEventType()==osgGA::GUIEventAdapter::KEYDOWN &&
(ea.getKey()=='d' || ea.getKey()=='D')){
bandera=0;
bandera=6;
return true;
}else{
return false;
}
}
private:
int acc;
};
struct AnimationManagerFinder : public osg::NodeVisitor
{
osg::ref_ptr<osgAnimation::BasicAnimationManager> _am;
AnimationManagerFinder()
{setTraversalMode(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN); }
void apply(osg::Node& node) {
if (_am.valid())
return;
if (node.getUpdateCallback()) {
_am =
dynamic_cast<osgAnimation::BasicAnimationManager*>(node.getUpdateCallback());
return;

}
};
int main()
{

if (!escena){
cout<<"I´m not reading"<<endl;
//exit(0);
}
AnimationManagerFinder finder;
escena->accept(finder);
const osgAnimation::AnimationList& animations =
finder._am->getAnimationList();
tankControll *eh=new tankControll();
osgViewer::Viewer visor;
visor.setSceneData(escena);
visor.addEventHandler(eh);
/*if(bandera==1)
finder._am->playAnimation( animations[1].get() );
else if(bandera==2)
finder._am->playAnimation( animations[2].get() );
else if(bandera==3)
finder._am->playAnimation( animations[3].get() );*/
visor.setCameraManipulator(new osgGA::TrackballManipulator);
visor.realize();
while ( !visor.done()){
//while (bandera!=6){
if (bandera==1)
finder._am->playAnimation( animations[1].get() );
else
if (bandera==2)
finder._am->playAnimation( animations[2].get() );
else
if (bandera==3)
finder._am->playAnimation( animations[3].get() );
else
printf("%i",bandera);
visor.frame();
}
return visor.run();
}
the problem is the follow: when i press the w after the q, or e, it seems that
animations are one over the other, why it happens?
...
Thank you!
Cheers,
Josue
