Flycam

[supr_k9]

hello everyone. i am currently working on a flycam for H2V. I have alot of it done but there is still ALOT of room for improvement. So far, it works great for still cam, but i am still working on making it perfect as a flycam.

here is a video of it so far:
http://www.kleep.com/Video-Games/H2v-Flycam.77565

as you can see, it is a work in progress. the camera moves in intervals of 1 and thats why it looks so jaggedy (if that is even a real word). I will make it smoother in the final version.

another problem you may have noticed is that the camera is always facing th same way!!! this is because i havnt found a way to make it look around (obviously) any suggestions? any help is appreaciated

i have:
-found the address that lets me go into flycam mode.
-found the address containing the X cooridnate of the camera
-found the address containing the Y cooridnate of the camera
-found the address containing the Z cooridnate of the camera

i have not:
-found the addresses containng the yaw, pitch, and roll of the camera (if it even uses yaw, pitch roll)

In the ifnal version, i will make the flycam controllable by both keyboard and 360 controller
if you have any suggestions, feel free to post

ahh finally a halo 2 vista flycam.

[jackson117]

so when is the flycam going to come out and what percentage to finsished is it

[supr_k9]

about 70% finished....well the one im going to release is already done...it was done a while back.. but im adding extra features to it that i WONT release... only certain people will have extra features.

normal flycam:
-flycam
-third person
-first person
-stillcam

extended flycam:
-flycam
-third person
-first person
-stillcam
-teleport to current camera coordinates
-increase running/crouching/jumping speed
-decrease running/crouching/jumping speed
-change field of view
-change contrast / brightness
-remove death barriers (just for the heck of it...even though it has nothing to do with flycam )

features i WANT to add but have no clue how to do
-everything yelo trainer for xbox did
-save checkpoint whenever
-load checkpoint whenever
-freeze everything
-well....im too lazy to name them all.....just go to

Its great that you make a Yelo for H2V.
But why do you make "Extra" functions and tell us which ?

Looks awsome keep up the great work!

Here's what I was able to dig up a while back...

Code: Select all

Halo 2 Vista Camera Addressing
-------------------------------------
0x8BD600	x camera coord
0x8BD604	y camera coord
0x8BD608	z camera coord
0x8BD60C	x camera shift (forward/back)
0x8BD610	y camera shift (left/right)
0x8BD614	z camera shift (up/down)
0x8BD618	horizontal look shift  (+counterclockwise -clockwise)
0x8BD61C	vertical look shift (+up -down)	
0x8BD620	camera depth
0x8BD624	field of view
0x8BD628	i forward look vector- cos(h)*cos(v)
0x8BD62C	j forward look vector- sin(h)*cos(v)
0x8BD630	k forward look vector- sin(v)
0x8BD634	i up look vector- negative(cos(h)*sin(v))
0x8BD638	j up look vector- negative(sin(h)*sin(v))
0x8BD63C	k up look vector- cos(v)

(disables perspective switch override)
move 0x909090 into address 0x459EBB

(enables perspective switch override)
move 0x89710C into address 0x459EBB

(disables writing to camera arrays)
move 0x909090909090 into address 0x482FA3
move 0x9090909090 into address 0x483091
move 0x9090909090 into address 0x4830C9

(enables writing to camera arrays)
move 0xD90410D91C18 into address 0x482FA3
move 0xF30F110C38 into address 0x483091
move 0xF30F110418 into address 0x4830C9

0x8A5288 - Perspective switch address (holds pointer to current perspective function)
0x00000000 = CameraUpdateNone
0x004CCFE4 - CameraUpdateFollowing
0x004CD681 - CameraUpdateFirstPerson
0x004CD9CF - CameraUpdateDead
0x00497EDD - CameraUpdateScripted

You can also take a look at some basic camera code I've been using in my directx testbed to get an idea of how the camera works in Yelo since they are very similar...

well what date you going to relarse the normal flycam for us.

and if its already done can we download it??

[CanadianPanda]

Jackson the answer to that question is: When he feels like it. Didnt you ever learn some people find it very irritating for you to ask for a release date. Here this guy puts a bunch of work into his flycam and your going to just run off with it and forget who even made it. If your going to use it and want it. Suport it dont be nit picky and just want a release. BE PATIENT like the rest of the community.


P.s. there was no yelling or flaming in that post!

[Patrickssj6]

xbox7887, that's great and thanks to you I finally understand everything

[jackson117]

let me quess if i turn flycam on while on LIVE even if im on SP maps it will think im cheating???

[supr_k9]

no you will be able to use flycam whenever without "it" thinking you are cheating. if you use it while on multiplayer, other people might think you are cheating, but they will have no way of knowing you are in flycam mode unless you tell them.


by the way.... what is "it" ?

Cool now we can make are own Red vs Blue style movies !
