CheckDirection Sub Question?

[Justn]

Hello guys I'm having an issue that I can't seem to solve on my own with this code..

```

' Check to see if a npc is already on that tile
For i = 1 To Npc_HighIndex
If MapNpc(i).num > 0 Then
If MapNpc(i).x = x Then
If MapNpc(i).y = y Then
CheckDirection = True
Exit Function
End If
End If
End If
Next

```
this is the code in a deafult eo to stop a player from walking on a tile with a npc on it.. The problem is that it only checks if they are on the same x or y so, left right up and down. I am trying to make it check all 8 sides surrounding a player but cant figure it out. I have tried lots of things but no matter what i change it just makes me walk through npcs from all directions.. Can someone help me out and teach me to check all 8 sides for an npc? =/

The x and y position in a 2D world represent the point,you can go to that point from either direction left right up down or vertical directions but still what you have to check is your x and y with the npc's x and y so,I don't see why it is a problem.

This doesn't specifically check left, right, up, down. It checks if anything is on the X/Y provided.

Ok thanks guys that makes more sense for some reason its not reading the x and y that are provided in the bit of code above that
