#Enum Question

“How could I get access to these, so that I could do the following:”

instead of

```
void AFPSCharacter::ApplyPowerUp(int32 amnt, int32 PUid)
{
    if (PUid == Health)
    {

```

do this!

```
  void AFPSCharacter::ApplyPowerUp(int32 amnt, const EPowerups::Type PowerUpType)
    {
        if (PowerUpType == EPowerups::Health)
        {

```

#Array Question

If you want to search through an array and find ID matches, you can do this:

```
//the ID to check for
int32 TheIDToCheckFor = 9000; //something;

for(const FCollectableID& EachCollectable : PUidentification)
{
  if(EachCollectable.ID == TheIDToCheckFor )
  {
     //found a match!
     //do stuff
     break; //if only wanting 1 match, ends loop early 
   }
}

```

#NEVER USE TYPE INT

in your struct:

```
int ID;

```

should become

```
int32 ID;

```

If you have more array questions please post a separate thread about it
