I have a problem with a code. I dont know what it means. I tried to multiply the value xmm0 before addsd instruction but the hack doesnt works. Actually How to multiply the value of address??
Y CO-ORDINATE

X CO-ORDINATE

I Just want the X and Y co-ordinate value to be multipled how to do

I am just reading up on assembly myself but the xmm0 register should contain a float value.

Have you tried fmul?

This is my code:

maybe fmul will be better? Im assuming its a single float value being stored in xmm0?

In the first picture, edx+4 contains the y co ordinate, debug that address and choose another code location that doesn't overwrite its value. You have chosen a pretty bad location to do injection considering you don't understand SSE instructions.

It would help if you post a screenshot of all the addresses that pop up when you debug the y coord

Your way in making super jump is wrong.
Think like a developer, every character has a static value that tells the game
how high you can jump.
The key in making a super jump / gravity hack is to find that static value.
On unreal engine based games that static value is usually stored inside the
player structure as a floating point value.
But in some occasions it's not, than reversing is the way to go.
Your way of breakpointing is right by breaking on the Y-coordinate.
Think like it this way when you jump the game has to decide if you jump higher than the staticly assigned value, if not you are allowed to jump.
Increasing that staticly assigned value you can jump much higher.
So you need to trace back the code to determine where the game is checking if you jumped passed the staticly assigned value.
For which game are you trying to make this?

Another thing to keep in mind, velocity. I know in some games the jump just sets your momentum on jump if conditions are met. So instead of debugging the Y value itself, try debugging the Y velocity.

I make a code just as above i just convert xmm1 and then multiply then convert.

I have no idea what your saying/ what you mean.
Which game is this for?

What you're doing won't make your player jump higher but simply make him float in the air until jumping out of map boundaries. All you're doing with that code is increase the value of Y (height) co-ordinate.

If you want to make a super jump, follow what veggy said. With that Y co ord, you can make a float mode option if you use some flags.
