<p>Hi, I am using a WinApi wrapper to ReadProccessMemory an address from a game. Here is the code I have so far.</p>
<p> </p>
<p>Here is me implementing it
<code>buffer, bytesRead, _ := w32.ReadProcessMemory(csgoHandle, newHealth, unsafe.Sizeof(newHealth))</code></p>
<p> </p>
<p>This is how I printed the data</p>
<pre><code>fmt.Println("This is data from the read proccess:", buffer,bytesRead)
for i := 1; i < len(buffer); i++ {
fmt.Println(w32.UTF16PtrToString(&buffer[i]))
}
</code></pre>
<p>and this is the result

<p>How can I interpret the data as something actually useful and legible? It will be a health value so I suppose it would be an integer?</p>
<p> </p>
<p>Here is a link to the wrapper I am using
<a href="https://github.com/AllenDang/w32/blob/master/kernel32.go" rel="nofollow">https://github.com/AllenDang/w32/blob/master/kernel32.go</a></p>
<p>and this is the code of the function</p>
<pre><code>func ReadProcessMemory(hProcess HANDLE, lpBaseAddress, nSize uintptr) (lpBuffer []uint16, lpNumberOfBytesRead int, ok bool) {
var nBytesRead int
buf := make([]uint16, nSize)
ret, _, _ := procReadProcessMemory.Call(
uintptr(hProcess),
lpBaseAddress,
uintptr(unsafe.Pointer(&buf[0])),
nSize,
uintptr(unsafe.Pointer(&nBytesRead)),
)
return buf, nBytesRead, ret != 0
}
</code></pre>
<hr/>**评论:**<br/><br/>JHunz: <pre><p>It's hard to tell exactly what's wrong with your code without seeing a bit more context, but here are some things to think about: </p>
<p>1) Are you sure you have the correct base address for the health value inside the process?<br/>
2) If newHealth is the correct base address for the health value you want to read (which it needs to be, per the API), then you are passing in the wrong size. The size should be the number of bytes you want to read, not the size of the base address.<br/>
3) You're ignoring the return value that tells you whether reading the value was successful or not. You probably shouldn't.<br/>
4) Once you're sure you're getting the right bytearray, it's pretty simple to convert to an int.
