Im making an fps, and use the arrow keys to move the screen. How would I go by making the mouse move the screen. Like you can look up down and all around then you can walk in the direction of the camera but stay on the floor...
Right now im using:

+ Code Snippet

do
if upkey()=1 then move camera 4
if downkey()=1 then move camera -4
if leftkey()=1 then yrotate camera wrapvalue(camera angle y()-4)
if rightkey()=1 then yrotate camera wrapvalue(camera angle y()+4)
x#=camera position x()
z#=camera position z()
y#=get ground height(1,x#,z#)+50
position camera x#,y#,z#

sync
loop

+ Code Snippet

OldCamAngleY# = CameraAngleY# 
	OldCamAngleX# = CameraAngleX# 
	CameraAngleY# = WrapValue(CameraAngleY#+MousemoveX()*0.2) 
	CameraAngleX# = WrapValue(CameraAngleX#+MousemoveY()*0.2) 
Yrotate camera CurveAngle(CameraAngleY#,OldCamAngleY#,24) 
	Xrotate camera CurveAngle(CameraAngleX#,OldCamAngleX#,24)

Use that in a do loop and you should be able to aim with your mouse

If you are using a matrix for the floor:

+ Code Snippet

  CX#=Camera Angle X(): CY#=Camera Angle Y(): CZ#=Camera Angle Z()
  CY#=Wrapvalue(CY#+mousemovex())
  CX#=Wrapvalue(CX#+mousemovey())
  Rotate Camera CX#,CY#,CZ#
  if upkey()=1 then move camera 4
  if downkey()=1 then move camera -4
  gh#=Get Ground Height(1,Camera Position X(),Camera Position Z())+50
  Position Camera Camera Position X(),gh#,Camera Position Z()

This moves with the arrow keys and steers with the mouse - always keeping you on the matrix. Alter the value 50 to suite the required height off the floor that you want.

TDK - It works but you can spin updside down to... how can this be fixed? Also how would you do gun bouncing and kickback.

To create my gun im using:

+ Code Snippet

`create gun and add texture
load object "Colt.3DS",1
yrotate object 1,0
fix object pivot 1
scale object 1,4500,4500,4500
position object 1,9,-9,14
lock object on 1
texture object 1,2

To keep it from spinning upside down, use something that detects if it is above 90 degrees. Like if camera angle x()=>90 then BLAH
As for the bouncing..........no idea.
