[CODE]How to move node to a specific position?

[weeix]

I'm trying to create a function that can move a node to any specific position.

Code: Select all

typedef struct
{
	scene::ISceneNode* node;
	core::vector3df current, destination, speed;
}movement;
irr::core::array<movement*> movementList;

void addMovement(scene::ISceneNode* node, core::vector3df& absoluteDestination) // This function runs as an event
{
	movement* movementInfo = new movement();
	movementInfo->node = node;
	movementInfo->current = core::vector3df(0,0,0);
	movementInfo->destination = absoluteDestination - node->getAbsolutePosition();
	movementInfo->speed = movementInfo->destination / 1000;
	movementList.push_back(movementInfo);
}

void updateMovement() // This function runs in every game loop
{
	for( u32 i = 0; i < movementList.size(); i++ )
	{
		movementList[i]->node->setPosition(
			movementList[i]->node->getPosition() + movementList[i]->speed);
		movementList[i]->current += movementList[i]->speed;
		if(fabs(movementList[i]->destination.X - movementList[i]->current.X) < 1)
			movementList.erase(i);
	}
}

but.. it doesn't work. I give up. [white flag]

Look at the code for FlyStraightAnimator produced from ISceneManager::createFlyStraightAnimator.

Look at the code for FlyStraightAnimator produced from ISceneManager::createFlyStraightAnimator.

I took a look in ISceneManager.h and only found this

Code: Select all

		virtual ISceneNodeAnimator* createFlyStraightAnimator(const core::vector3df& startPoint,
			const core::vector3df& endPoint, u32 timeForWay, bool loop=false, bool pingpong = false) = 0;

(I'm trying to integrate your "ease in/ease out" method with the function.)

I think he meant to find it in the irrlicht source, so you could see the code. Anyway, I don't see anything fundamentally wrong with your code. Have you tried to see if speed actually has a value that isn't 0,0,0? And also, be sure to use a frameDeltaTime value for movement if you plan on keeping frame rate independence.
