Help/Support How to Hook this function?

[nyc709 1 iPad Mini 4 11.4.1]

Can somebody help me hook this function to repeat itself. Like I'm doing attack multiplier to hit the enemy multiple times.

[Address(RVA = "0x1639E4C", Offset = "0x1639E4C", VA = "0x101639E4C")]
public void SendAttackToEnemy(List<int> moblist, int skill, int card, int flag)

 

#import "Menu.h"
#include <substrate.h>
#import <mach-o/dyld.h>

uint64_t getRealOffset(uint64_t offset){
return _dyld_get_image_vmaddr_slide(0)+offset;
}
int (*org_SendAttackToEnemy)(void*, int moblist, int skill, int card, int flag);
int SendAttackToEnemy(void* this_, int moblist, int skill, int card, int flag) {
  return org_SendAttackToEnemy(this_, moblist, skill, card, flag) * 20;
}
%ctor {
  MSHookFunction((void *)getRealOffset(0x101639E4C), (void *)SendAttackToEnemy, (void **)&org_SendAttackToEnemy);
}

 

Kindly correct my code cause it's not working. planning to repeat the function 20 times.
