Method for Measuring Distances & Velocity in MW2

[fred]

Think I have a method for measuring distances & velocity in MW2. It depends on whether we have any known distances of objects in MW2. For COD4 Den has info that the large containers (like those in Shipment) are exactly 256 x 100 units/inches dimensions. If those dimensions are still true then you can figure out the velocity of the avatar, but you've got to be careful to use some standard condition. So went to Sub Base and timed my avatar running at maximum (but NOT sprinting) past 1 container (long ways) using a stopwatch. Then used the equation: distance = velocity * time in reverse to find velocity from assumed distance and measured time.

MEASUREMENTS

Class	Avg Time 256 "inches"	Correction Factor	Corrected Time
SMG	1.595 s	1.0 (none)	1.595 s
AR	1.64 s	.95 (none)	1.56 s
MG	1.82 s	.875 (none)	1.59 s
	Overall	Average	1.58

CALCULATED VELOCITY of AVATAR

Primary	Condition	Assumed Coeff	Inches per sec	MPH
MG	Normal	.875	142	8.1 mph
AR	Normal	.95	154	8.75 mph
SMG	Normal	1.0	162	9.2 mph
SMG	Sprint	1.5	243	13.8 mph
SMG	Sprint/LW	1.65	267.3	15.2 mph

These velocities can be use to measure distance using a stopwatch!

NOTES:

* TESTED on PS3 in split screen mode
* Took 6 times for each class; discarded high and low and averaged rest.
* Always running directly forward, not jumping either
* Tried to minimize parallax.
* Did not use lightweight or marathon
* Did not sprint at any point.
* Tried to accelerate to maximum immediately
* I used 3 classes, SMG, AR and MG. As you can see from the "Corrected Times" above using the known coefficients 1, .95 and .875 for movement speed they are pretty consistent.
* Used 1 MPH = 17.6 inches/second

FURTHER QUESTIONS:

* What are the dimensions of the maps?
* What is the velocity of the skill tube grenade, AT4 or RPG? Shoot one at a distance and stopwatch how long it takes to hit. Measure that distance divide by time and you'd get an average horizontal velocity for the projectiles.
* I have another post regarding weapon ranges. I want to use this method to cross correlate the distance of the RR ties on the track to "inches".
* I cannot check myself now; my son is visiting relatives and I let him take the PS3 with him.

Good research there Fred.

One point about measuring velocity of the n00b Cannon is that it's distance is based upon angle of firing therefore you need to accurately be able to judge a 45 degree angle of release in order to obtain max range, assuming that the shot is based upon level-to-level ground.

if it helps, the carts of the train on derail has writing on it which sais each cart is 10metres long
well ive been told that

nice work bro, I'd like to see the speed of the care package and whether or not lightweight even affects it.

Maybe I'm just interpreting wrong, but I don't see how that would matter

velocity is a vector component of x, y, velocity.

x velocity is constant, y is changing because of gravity (assuming CoD uses gravity, could be possible that all objects have the same falling speed though idk)

The time it takes for a launched grenade to hit the ground is the same as the time it took to travel x distance
