moveTo changes target incorrectly #514

Open richfwebb opened 5 months ago

richfwebb commented 5 months ago

In some cases, moveTo moves to an incorrect position.

Using this example, https://yomotsu.github.io/camera-controls/examples/basic.html

Press the buttons: 

moveTo(3, 5, 2)
lookAt(3, 0, -3)

Then repeat, and you can see the camera position keeps growing. This doesn't seem the intended behavior.

There's also a separate sequence of presses where the camera stops moving at all, if you experiment, no matter how many times you hit moveTo(3,5,2) or moveTo(-5,2,1). Maybe I misunderstand this method, and this is expected.

On a related note, how to correctly move the camera for third person view of a moving character that updates each frame? Maybe could add this to the docs?

I tried: moveTo, setTarget, add the camera as a child of a target object, etc. still not really sure what's right. Thanks for this great library btw!

To Reproduce

Steps to reproduce the behavior:

  1. Go to '...'
  2. Click on moveTo(3, 5, 2), then click lookAt(3, 0, -3), then repeat
  3. See error
