Key input in Irrlicht

[mtbal]

How do I get key input in Irrlicht? They do it in the Terrain tutorial, but that is when a key is tapped. I want it to check in the main loop to see if a key is pressed, and then do my code. (I'm trying to make it so that when I hold a key down, the node is rotated.) BTW this is in C#. But I can prolly translate any C++ code.

Thanks!

Check example 4, IIRC that's the tutorial with the key array method in the receiver.

Sorry, but that still moves when the key is clicked. Any other ideas?

Irrlicht doesn't have a function for determining key state. Instead, you need to keep track of it yourself. Like hybrid mentioned, an example of how to do so can be found in 04.movement. See IsKeyDown():

Code: Select all

	while(device->run())
	{
		// Work out a frame delta time.
		const u32 now = device->getTimer()->getTime();
		const f32 frameDeltaTime = (f32)(now - then) / 1000.f; // Time in seconds
		then = now;

		/* Check if keys W, S, A or D are being held down, and move the
		sphere node around respectively. */
		core::vector3df nodePosition = node->getPosition();

		if(receiver.IsKeyDown(irr::KEY_KEY_W))
			nodePosition.Y += MOVEMENT_SPEED * frameDeltaTime;
		else if(receiver.IsKeyDown(irr::KEY_KEY_S))
			nodePosition.Y -= MOVEMENT_SPEED * frameDeltaTime;

Another way to handle this is to track the key's last state. In a demo I wrote I kept track of boolean's for the key press. If the next time it went into the event receiver and I still had the "a" key pressed; boolean stillPressed = true; And than after that I would do my world manipulations.

so....

//Global variable
boolean wPressed = false;

//function
if (receiver.IsKeyDown(irr::KEY_KEY_W)) {
wPressed = true;
}

if (wPressed) {
nodePosition.Y += MOVEMENT_SPEED * frameDeltaTime;
}
