[EO] Walking through players

[Guest]

At the end of this tutorial your players will be able to walk through each other but ONLY on Safe maps.

First, in Function CheckDirection find this:

```
' Check to see if a npc is already on that tile
```
And move that whole chunk of code (up to 'Next) above:

```
' Check to see if a player is already on that tile
    For i = 1 To Player_HighIndex
        If IsPlaying(i) And GetPlayerMap(i) = GetPlayerMap(MyIndex) Then
            If GetPlayerX(i) = x Then
                If GetPlayerY(i) = Y Then
                    CheckDirection = True
                    Exit Function
                End If
            End If
        End If
    Next i
```
What this has done has allowed us to not let players walk through NPCs (you'll see why later).

Next, add this:

```
If Map.Moral = MAP_MORAL_SAFE Then Exit Function
```
Above:

```
' Check to see if a player is already on that tile
```
Now that line of code tells the game to ignore the check that checks whether another player is already on the tile IF the map is a safe map. Now you can see why we put the NPC on the same tile check above that line, so it doesn't also exit out.

And thats it, goodluck!

Nice, thank you.

Wouldn't it be only on safe maps?
```
If Map.Moral = MAP_MORAL_SAFE Then Exit Function
```I could just be reading into it wrong though, it is late at night :P

[Guest]

Yeah.. too early for me too xD. Meant safe maps.

I can't find Sub CheckDirection, Is this for EO 2.0?

> I can't find Sub CheckDirection, Is this for EO 2.0?

Yes. Make sure you hit the Entire Project radio button with CTRL+F.

[Guest]

My bad again, its Function CheckDirection.

[Grimnnak]

Still cannot find it.

[Grimnnak]

is it in Server or Client, because im looking in Server.

[Guest]

Its in modGameLogic, just do ctrl f and click "Search whole project". Its client side.

[Grimnnak]

Oh Doi to me, I thought all Moving functions would be handled in Server, Thanks.

[Grimnnak]

Okay, now i have a problem, I am able to walk over NPC's, and They don't attack back. What do i do?

[Guest]

…. The first step in the tutorial is done to avoid that happening...

[Grimnnak]

Ok,I can't walk thru NPC's, But they don't attack back now

[Grimnnak]

Heres what the codes looks like…http://i55.tinypic.com/r2l3t4.png

[Guest]

Them not attacking back has nothing to do with my code, you've bugged up your own source.

[Grimnnak]

Never mind they attack back, Thanks…

[crzyone9584]

Thanks sekaru. You saved me a lot of work. I was going to eventually get to this for kins game.

[Guest]

S'alright mate.

[Whackeddie99]

doesnt work for me it says Compile error:  for control variable already in use

Help!

[Guest]

Then you're not doing it right.

[Whackeddie99]

i did it exactly as it said. Maybe its interfering with other coding from other things added into it?

[Gwen]

eddie… why dont you post your code so we can make sure you have everything correct.

did you change anything else in that section of code? Try commenting out this section of code and see if you still get the error.

that error is due to one of your for loops not terminating correctly.

@Whackeddie99:

> i did it exactly as it said. Maybe its interfering with other coding from other things added into it?

It has nothing to do with any other line of code in EO. It's simply moving a block of code above another block of code and adding a line under that.

And yeah, try what Gwen said.

[Whackeddie99]

I got it to work im just a freaking retard and i messed up somewhere, thanks :)
