Zoom scope slowing down mouse
2003-01-03, 10:51 PM #1
For ages I have been getting annoyed at the head pitch which JK features, seems like LEC forgot to add a few verbs or something. One thing which was greatly effected was the ability to adjust the Z axis position or speed, which is very essential to the success of a zoom scope.

Anyways this afternoon I sat down and attempted to re-address the issue. This is what I came up with. Its far from perfect but with alittle more coding and stuff it will be ok. The coding behind it isnt very hard so most people will be able to understand it. (This cog is the bryar, right click to zoom in, right click again to zoom out) Sorry about some of the comments, their alittle incomplete.

http://24.46.164.108:81/jkteambattle/images/media/weap_bryar.cog

I need some help with this (btw feel free to use it how you like, if you find it useful). I need to make it so you cant zoom through walls and get the mad homs and stuff. I also need to improve movement on the z axis (Its still buggy)

Heres the bulk of the code:

[edit]The code tags suck, d/l the cog to read[/edit]

Thanks.

While there are loads of other very useful new verbs in MotS, the main reason I chose to edit that over JK was the zoom verbs. To me, the zoom solutions that have been presented for JK thus far have been far to buggy and clumsy. But maybe you can change my opinion.

I haven't downloaded the cog, but I'm assuming you're using an eyeoffset. Why not fire a projectile through a pulse and have that projectiles explosion, or removed message report its position to the weapon cog. Then you can calculate the distance the eyeoffset should be and prevent it from going through 3dos. This should all be done locally of course.

I did it!

Code: 
# Jedi Knight Cog Script
#
# WEAP_BRYAR.COG
#
# WEAPON 2 Script - Bryar Pistol
#
# The trusty weapon of Kyle Katarn. This is actually an older modified rifle
# that has been cut down to more of a pistol size. It is very accurate but
# somewhat of a low power weapon. This weapon has only one type of fire.

i noticed a fov=(i think 70?) thingo in kyles actor template

i couldn't get it to change the fov around though, and the fov listed there might have been for LOS calculations for force-grip and pull and stuff
