 Posted: Sun Apr 02, 2023 1:15 pm Post subject: Can I Run A Script And Then Kill It? |
 |
|
I'm creating a large life bar script for Metal Gear Solid which extends the life gauge across the screen, but Actual Life doesn't fill it up within the bar automatically like I want. I created another script for your Actual Life to match your Max Life and placed it inside the High Life Bar script.
The issue is this match life script makes me invincible. Is there a way to only run it once in the script so that I get the HP to match without becoming invincible?
I'm aware there may be a way to kill it, but after searching around I just can't seem to find the tutorial required to help me get my syntax right. Also, if there is an alternative way to make this happen in CE please let me know.

You can create a trigger inside of the script that gets set anytime you press the hotkey for it (boolean), then it resets itself when the action is tiggered. This can be repeated as much as you want.
example:
| Code: | newmem:
cmp byte ptr [trigger],1
je set_health_to_max
jmp originalcode
set_health_to_max:
mov byte ptr [trigger],0
//code for setting health value to max
jmp originalcode |
You will need to perform a few extra steps in order for this script to work properly. If you paste your script in text format, I can fix it for you so that you can see how to set everything up and study it.
Otherwise, there are ways to do this with Lua.

Wow thanks I'll post it below!

}

[ENABLE]
assert(address,bytes)
alloc(newmem,$1000)
label(code)
label(return)
newmem:
code:
push ecx
mov ecx,[mgsi.exe+38E7F8] //MAX HEALTH
mov [mgsi.exe+38E7F6],ecx

pop ecx
jmp return
address:
jmp newmem
nop 2
return:
[DISABLE]

db bytes
// movsx edx,word ptr [mgsi.exe+38E7F6]
dealloc(newmem)

I am interested in learning LUA for CE and how this would look like for that.

I'm surprised that code works. You should probably be treating those as 2-byte values instead of 4-byte values...
Regardless, this is how to read and write a 4-byte value in Lua:
| Code: | local maxHealth = readInteger('mgsi.exe+38E7F8')
writeInteger('mgsi.exe+38E7F6', maxHealth) |

I just woke up, so you will want to test this before studying it.
https://ufile.io/3n3alg2r
Once the script is activated, you should be able to set the 'Heal' entry value to 1 in order to trigger the effect. You can set up a hotkey for this that can trigger the effect using the keyboard or controller etc..
