ok, ive been having problems with this for a long time, i want to have a gun but placed at the side of the character, not straight infront, i could just lock on the positions but then the bullet doesnt come from there, so i used the code from the examples (the smooth curve camera code) and instead of doing it with the camera i did it with the gun, now i can make the bullet come from it, but the gun never stays in the same place, and i cant make the gun tilt up and down coz when the camera's facing the other way it turns the wrong way.......

In short words: can anyone help me position the gun to the side AND make the bullet come from it?

EDIT: Its a first person shooter just so u know...

thanks

gday

you could set the object offsetted (i know you can do this in truespace 3.2) and rotate it off the center of the camera maybe. as for the bullet you would probably have to play around to do something like that

heres an example though

if bulletfired=1
position object camerax,cameray,cameraz
rotate object camera angle x, camera angle y, camera angle z (or you can put 0 for angle z which is probably better off)
turn object right (bullet),90
move object (bullet),(how much to the side you might need to experiment here)
turn object left (bullet),90

this should position the bullet where you want it. if this isnt clear email me and ill clear it up for you

ps: without offsetting the guns position it might not work

pps: i have actually tried this in my game and it works to an extent

cheers

Yes i once got that prob too.
I believe there's a forum where they recommend of starting the bullet at the same position of your camera and moving it so fast it can't be seen by the camera.

if you did not want to see your bullet you could always hide it and save alot of trouble.

now i noticed that it looks kinda crap, but im bored with just a round bullet that goes dead slow, what i mean is that i wanted to see the bullet flashing out of the gun...*not now alastair, your still not good enough*...bleh

EDIT: Oh yeah, i forgot to say, without locking on the guns position, how do i make it turn round the x axis with the camera(so if i look up its still there), it does it fine when i face one way, but when i turn 180 deg, it turns the wrong way

You want to make your bullet flash out of your gun right?
Just make a special effect on the moment you shoot.
You know... plains...

By the way... if you are using my way bullet-positioning. You CAN use the "lock object on" command.

ah cool, ill try that, thanks

edit: does this mean that u dont even have to have a bullet object, just a bunch of changing coordinates?

Zotoaster,

I come to the same problem with Euler rotation as you. That if I'm facing at 0o on the Y axis and my gun is angled at 45o(upward slant) on the X axis, as I turn the player on it's Y axis, though I technically have not rotated the gun myself, it will rotate downward. So, when I am faced at 180o on the Y axis, my gun is pointing at ,I say about 135o(downward slant).

nah, my problem is slightly different, i can turn it with the camera round the Y axis, but if im facing straight and turn the camera round the x axis, the gun does too, but if im turn 180o round the y axis and turn round the x axis, the gun goes the opposite way

ah yeah, i must've not read it properly, sorry

Edit: Since I'm here Id also like to ask soething else...
uhh, ok, im not using bullets (well i am, but you just cant see it), but id like to somehow change that, like, just make coordinates that always change when you shoot, coz if i use a bullet and just do "Move object 4,10000" or w/e, it sorta skips over 10000 places all the time (i think) and makes it sort of tricky to shoot the enemy...and i also dont like it how it can only go a certain distance.....so how would i make a bunch or coordinates that always change instead of using a bullet, AND make it go an infinite distance and while these coordinates are changing you can shoot again?
