Can anyone help me with my coded hack?

#include "windows.h"
#include "process.h"

#define WeaponMgr  0x1421D74
#define wallclass  0xA6910C
#define NoReload  0xECC


void MatheusGtx(){

    DWORD CShell = (DWORD)GetModuleHandleA("CShell.dll");
    DWORD pWeaponMgr = *(DWORD*)(CShell + WeaponMgr);
    DWORD pWallClass = *(DWORD*)(CShell + wallclass);
    DWORD dwCShell = (DWORD)GetModuleHandleA("CShell.dll");

    if (pWallClass) {
        for (int i = 0; i<64; i++) {
            *(float*)(pWallClass + (i * 0x04F4) + 0x4E8) = true;    
            *(float*)(pWallClass + (i * 0x04F4) + 0x4EC) = true;   
            *(float*)(pWallClass + (i * 0x04F4) + 0x4F0) = true;  
        }
    }

    if (pWeaponMgr){
        for (int i = 0; i<577; i++){
            if ((*(DWORD*)((*(DWORD*)(CShell + WeaponMgr)) + (4 * i))) != NULL){
                *(float*)((*(DWORD*)((*(DWORD*)(CShell + WeaponMgr)) + (4 * i))) + NoReload) = 100.0f;
            }
        }
    }

}
