Hi, it would be great to have smooth camera keyboard (W,S,A,D or L,R,U,D) inputs instead of the Windows key repeat. Currently when you move through the scene you have to wait up to 0.5 seconds before the camera finally moves again on every single input. It's also not precise enough to be useful to step through the scene like this and for precision we already have Shift + Right Mouse Button (zoom).

I vaguely recall having this issue (years ago) on a certain nvidia card. Switching the 3D camera controls to use arrow keys for input was (for some reason) smoother if I recall correctly. Have you tried that?

Hi Henry00, welcome to these forums! Smile

Have you tried the Level Preview Plugin found in the Extensions section on the website? That might help.

I use the mouse wheel for zooming, if that helps.

Right I must apologize for the late reply, I tried switching from WSAD to the Arrow keys but there were no changes, sure the camera zooming is a good idea it pretty much takes care of it but obviously it's not like playing a First Person Shooter (WSAD + Right Mouse Button) which I love.

To fix this problem from the developer's perspective you would only have to make 4 boolean values and do something like this:

Code:
bool key_w;

when "w" is pressed:
     key_w = true;

when "w" is released:
     key_w = false;

on program update:
     if key_w then:
          move camera forward.

You can alter the key repeat timings and perhaps make a hot key to swap settings. The 'delay' is simply to prevent false multiple key presses. Use the sliders in the Keyboard settings in the Windows Control Panel.

I use the RMB and set to use WASD in settings, I can fluidly move about any scene.

Did you try the Level Preview Plugin Jeroen suggested? I've used it to get a feel of perspective and scale in many of my scenes. Works quite well.
