Keyboard Input - Smooth And Multiple keypress

[ktyrer496]

hi,

Im trying to make a ship move, and i need it to move smoothly, but now it move one bit at a time and looks really silly and bad, like a jerking motion. also how can i make it so i can press more than one key at a time so that the ship can move diagnally rather than just left then up etc..

my code is as follows:

class MyEventReceiver : public IEventReceiver
{
public:
//============================================CONTROLS================================================
virtual bool OnEvent(SEvent event)
{
if (event.KeyInput.Key == KEY_KEY_A)
{
core::vector3df v = Munch->getPosition();
v.X += -2.0f;
Munch->setPosition(v);
}
return true;
}
};
//=============================================CONTROLS END=============================================

Any help would be appreciated

regards

Search for bool keys, or click one of the links below...

The gist of it is that you just capture the key states in the event receiver. When a key is pressed down you set a flag, and when it is released, you clear the flag. Then, in the game loop, you check the state of the keys and do something based on their status.

If you download the latest SVN version, example 04.Movement has been updated to demonstrate storing key states.

Yup. The first link in that list is to the patch you posted last week.
