Hi All,
I am making a shooting range. I don't like using (Lock object on)
to keep the weapon locked to the screen. I hope some one can tell me a better way of doing it.
Thank You

I just position it in front of the camera, rotate it every loop (and disable z-depth at the beginning)

This way the lighting still affects it

I can't get the camera and object to rotate togather.
here is the code

+ Code Snippet


autocam off

set image colorkey 255,0,255

sync on

srate=60

sync rate srate

color backdrop 0


set camera range 1,2500
position camera 0, 10,0

set ambient light 30
load image "grass.jpg",1
make matrix 1,300,700,20,20
position matrix 1,-150,0,-480
prepare matrix texture 1,1,1,1
update matrix 1



load object "sig.dbo", 1
`lock object on 1
position object 1, -0,10,45
scale object 1,20,20,20
rotate object 1,0,0,0

do
set cursor 10,10
print SCREEN FPS()


position camera object position x(1),object position y(1),object position z(1)-7


If keystate (17)=1 then move object 1,-.5
If keystate (31)=1 then move object 1,.5



Sync
sync
loop

I am not sure how to make them rotate on the same plain.
Thank you

Try this logic:

1. Position and Rotate Camera
2. Position and Rotate Weapon to match camera
3. MOVE OBJECT to shift the weapon forwards in front of camera.

This is very simple logic, but it removes anything complex and confusing.

You also have 2 SYNCS where you only need 1.

WelL I have been working on this for the a day now,and still I can not make it work.
Here is my code,

+ Code Snippet

autocam off

set image colorkey 255,0,255

sync on




set camera range 1,2500
position camera 0, 10,0

set ambient light 30
load image "grass.jpg",1
make matrix 1,300,700,20,20
position matrix 1,-150,0,-480
prepare matrix texture 1,1,1,1
update matrix 1
yrotate# =1+1


load object "sig.dbo", 1
`lock object on 1
position object 1, -0,10,45
scale object 1,20,20,20
`rotate object 1,0,180,0

do
Rotate Camera Camera Angle X()+MouseMoveY(),Camera Angle Y()+MouseMoveX(),0
rotate object(1),object angle x(1)+MouseMovex(),object Angle Y(1)+MouseMovey(),0
position camera object position x(1),object position y(1),object position z(1)-7


If keystate (17)=1 then move object 1,-.5
If keystate (31)=1 then move object 1,.5





sync
loop

I sure some one out there know how to put a waepon on the screen so it does not move. But maybe not.
Thanks
