 |

Hey guys, back again. This time I don't really need help but would like brutally honest opinions from people who have more experience than me.
For starters, the game of the day is darksiders 2.
I finally finished my jump hack (actual jump hack not just changing coords), however, I feel as though my code is sloppy and could be improved as it does use a lot of repetition(still proud of it though as it's my first actual jump hack)
------Register TOC---------
[ebx+08] == Z coord
[ebx-9c] == StaticVelocity
[ebx+110] == The best jump indicator I could find(like %95 perfect -- slight issue when at the top of a climb but not serious)
------------------------------
Truthfully the code works nearly flawless and I am happy with the effect. Now I am just wondering if my code is about as clean as it gets or if it could use some housekeeping
(side note, the reason for the check in height instead of just a jump check is because I want gravity to return to normal at the top of the jump. It feels kind of weird with low velocity throughout the whole jump as the velocity changes everything eg. X/Y movespeed, and even character model rotation)
As usual, crack the whip if necessary haha.
***BAH! EDIT-----
I meant to also mention that the code I chose to inject a also modifies like 10 other addresses that would crash the game if modified however the Z-Axis address is the only one with a float value of 1.0 or 0.35 at -9c. Also, seeing as the game uses velocity, I imagine that upon jumping, your are launched into the air using a static value for "force". the value increases by roughly 55 before descending on a normal jump but I simply could not find that value. Am I wrong in my thinking? It would be a lot simpler to just modify the launch force in my opinion ... if possible...
