Question

I’m developing a side-scroller game like Super Mario. I’m trying to move a character using setLinearVelocity(), but this doesn’t seem to work properly. When the character falls and then starts moving, he doesn’t continue to fall but only moves.

This is a code snippet:

Sprite backward = new Sprite( -50, CAMERA_HEIGHT - 170, backwardr){
    @Override
    public boolean onAreaTouched(TouchEvent pEvent, float pX, float pY){
        if(!pEvent.isActionUp()){
            charactersprite.getTextureRegion().setFlippedHorizontal(true);
            body.setLinearVelocity(new Vector2(3,0)); // There's the problem

        }else{
            body.setLinearVelocity(new Vector2(0,0)); // Don't look at there
        }
        return false;
    }
};

Could anyone please help me?

I fixed it with :

Sprite backward = new Sprite( -50, CAMERA_HEIGHT - 170, backwardr){
    @Override
    public boolean onAreaTouched(TouchEvent pEvent, float pX, float pY){
    if(!pEvent.isActionUp()){
        charactersprite.getTextureRegion().setFlippedHorizontal(true);
        body.setLinearVelocity(new Vector2(3,body.getLinearVelocity.y)); // There's the problem

    }else{
        body.setLinearVelocity(new Vector2(0,getLinearVelocity.y)); // Don't look at there
    }
    return false;
}
};
