Making a flashlight.

[disanti]

Code: Select all

//flashlight
		case INPUT_F:
			flashlight = !flashlight;
			if(flashlight)
			{
				//make the player light
				playerlightnode = gProc.smgr->addLightSceneNode(camera,
					droid.position, 
					irr::video::SColorf(1.0f, 1.0f, 1.0f, 1.0f), 50.0f);
			}
			else
			{
				playerlightnode->removeAll();
			}
		break;

This crashes if I press F (to turn the flashlight on). Is there any knowledge of a better way to do this?

I pasted your code into my application and it worked fine. Any other details? Such as, which is the line that causes the crash?

Of course, I'm going to assume you've initialized your flashlight variable to 0, false, etc. I did as well, and no crashes.

Otherwise, if it's a random value at game start, flashlight will be toggled to 0 right after you case INPUT_F: line...and since playerlightnode is probably unitialized at that point, doing a removeAll() is not valid.

Oh, thats why it wasn't working! I figured out a faster method anyway, that is to position the light WAY out in the middle of nowhere and then position it back when needed.
