A simple script to rotate the camera Z angle while strafing left or right.
Two scripts really, first one is a "rigid" rotation, quick and fast. The second script is a more smooth transition with a natural movement.
Axis has been corrected but can be easily changed. Also amount of axis movement can also be adjusted.
Have fun, play hard

Quick rigid rotation...

+ Code Snippet

:state=0:state=1
:state=1,scancodekeypressed=30:state=2
:state=1,scancodekeypressed=32:state=3

:state=2:setvar=$CAZ 15,state=4 
:state=3:setvar=$CAZ -15,state=4
:state=4,scancodekeypressed=0:setvar=$CAZ 0,state=1

Smooth natural rotating movement...

+ Code Snippet

:state=0:dimvar=camz,setvar=camz 0
:state=0:state=1
:state=1,keypressed=30 1:incvar=$CAZ 1,addvar=camz 1,state=2
:state=1,keypressed=32 1:decvar=$CAZ 1,subvar=camz 1,state=3

:state=2,keypressed=30 0:setvar=$CAZ 0,setvar=camz 0,state=1
:state=2,varnotequal=camz 10:state=1
:state=2,varequal=camz 10:state=6

:state=2,keypressed=32 0:setvar=$CAZ 0,setvar=camz 0,state=1
:state=3,varnotequal=camz -10:state=1
:state=3,varequal=camz -10:state=7

:state=6,keypressed=30 0:setvar=$CAZ 0,setvar=camz 0,state=1
:state=7,keypressed=32 0:setvar=$CAZ 0,setvar=camz 0,state=1

Video show both scripts working ....

That really does add something to strafing. Very cool. Thanks.

This is cool! Kinda reminds me of quake 1.

The idea to tilt the camera while strafing is great, it looks more immersive. The problem came from the Z axis, because it's world oriented. Mriganka also noticed this issue
https://forum.thegamecreators.com/thread/220231
The Z axis must be relative, oriented to the player's camera.
ncmako why you're looking only in one direction in the video? Spin around and you will see how "$CAZ" actually works. When you turn left or right, the lean effect makes you look up and down. When you turn 180° the lean effect is mirrored and left movement force you to lean to the right...

@ Dark Lord I see what you mean, yes. Time to try and debug a little.

Yes yes yes!!! I hope the debugging leads to an answer because this will add so much to gameplay experience! So badass! This is a perfect example of how unlimited the engine can be when you think outside "the box!" I don't see fpsc dieing anytime soon.
Edit:
I have made a fpi file, used it as main, placed this code snippet in the playerinzone, and even ctrlc+v'd it into "when used" and i have decided that i must be a complete nit wit because I cant for the life of me figure out how to even get the cam to do what you did with it. Trigger zones they say...
Wish I still had my

Edit: I was looking in the syntax manual and I see there is playercamoffset listed, perhaps the engine would accept playercamrotz=x

@ SolaraV Yes, just copy the code snippets & save to your scriptbank, then attach to a triggerzone and place anywhere in the level.
Test run and the A & D keys (left & right strafe ) will trigger the script

Also, might have something better script wise. Been testing using additional axis. Dark Lord is correct, the camera is world oriented
and not player. So that is a problem.

If they are working on Black Ice Mod perhaps they could implement a player-centric axis system. But for now, I would suggest creating dummy variables and then changing the axis (X or Z) to make it look like leaning. But then there is this problem with the X-axis being locked because of how it works with the mouse. Even increments don't work as they become the new default value for the X-axis once added.

So unless someone is willing to work on the source, there are no proper solutions to it, unless you want to make the entire game along the Z-axis.

That would explain it ncmako, I saved the new FPI's on the desktop, didn't think it made a difference where they were as long as they were pointed to in the engine...

Mriganka, anything is possible with love...

is flat in every 3d modeling program I've ever used.

All of the camera rotations are in world space so it's a nightmare to try and have good tilting effects.

If something compiles on the first try. Something is terribly wrong.

Ok. Here's an idea, but it's incomplete. I don't reallly understand enough about the language yet, but something like this?

+ Code Snippet

:state=0:state=1
:state=1,scancodekeypressed=30:state=2
:state=1,scancodekeypressed=32:state=3

:state=2:setvar=$CAZ 15,state=4 
:state=3:setvar=$CAZ -15,state=4
:state=4,scancodekeypressed=0:setvar=$CAZ 0,state=1
setvar=$CAX=180
:state=2:setvar=$CAZ -15,state=4 
:state=3:setvar=$CAZ 15,state=4
:state=4,scancodekeypressed=0:setvar=$CAZ 0,state=1

Edit: just tested this and it actually works somewhat, just needs more variables. To fix the 90 & -90 degree view
Edit, no maybe I was wrong. I'm actively digging in to this to achieve a workable solution. But I can't figure out the correct way to phrase this so that the engine understands. Tried multiple ways. Attached is a pic

@ Mriganka & Uzi Yes, you guys are both correct. It's a frustrating problem to overcome. All the axis come into play.
@ SolaraV I think I know what your after. Keep plugging away at it. If anything you will begin to understand the fpi script language much better
what it's able to do.

I probably tried 300 combinations tonight and so far I am unable to come up with anything that works, except once I was upside down and it kinda worked...
Btw, I came up with a hardware solution, place an electrical actuator under each side of the tv, an have them activated by a&d keys so the screen tilts when you strafe...ghetto but, for an extra 30 bux in hardware you could include the rotz package to the end user.

Edit: what about the mouse look function? Can this be manipulated? $MMY $ MMX are both in the syntax list, can $MMZ be called and is this even relevant as an idea? Doesn't mouse look operate separate from the camrot ?

Update: I find a value of 2 to be very tolerable in all directions when using the script. So although we have been unable to solve this, $CAZ 2 & -2 adds a bit of looseness and doesn't mess up your aim vertically too much when facing either side. So I call this a win! the 2 degrees of vertical movement could actually help a player if they are aiming slightly high or too low if they switch strafe directions right before taking the shot.
