[Resolved]Picking up items order (HELP D:)

[DopeyBiach]

When there is more than one item on the same spot on the map and you pick the item up.. It picks up the bottom item first? I can't seem to find the code to change this anywhere  .. So say if your standing on a log and a fish.. The log is UNDERNEATH the fish.. However you still pick up the log first.. How do I change this? Thanks.

It's something to do with map item indexing i believe, i fixed it one but that was awhile ago. Might try and dig up the code.

[DopeyBiach]

Thanks, I've looked for ages, but can't seem to find any relative coding, will have a further scan 

[Ecto]

I think it's somewhere in the sub

```

CheckMapGetItem

```

I'm not sure though, I'd have to look.

[DopeyBiach]

I've looked there lol, I'm most likely missing something and it's bound to be something irritatingly obvious.

Just turn the render sub around, make it go from high to low. The pickup code picks up the first item it can find in the UDT, but the render code layers these, so 1 will be rendered first, 2 on top of that etc. That's how this is caused.

So… I did a long complicated process of indexing the map items for nothing?

[DopeyBiach]

In what sub exactly does the rendering for mapitems take place.. If it's BltItem or Render_Graphics I can't see it.. Urggh, I'm tired lol..

Pretty much yes. Could've done it far easier and just adjusted the render order.

BltItem, HOWEVER the order of it is determined in Render_Graphics:

```
' Blit out the items

If NumItems > 0 Then

For i = 1 To MAX_MAP_ITEMS

If MapItem(i).num > 0 Then

Call BltItem(i)

End If

Next

End If
```

[DopeyBiach]

I've seen this line so many times and ignored it LOL.. So how would I change that so the order was from high to low? Sorry, last question I swear :L.. At least I'll know this in future.. Thanks again 

[Joyce]

Written from the top of my head:

```
if NumItems > 0 then

i = MAX_MAP_ITEMS

Do While i > 0

If MapItem(i).num > 0 then

Call BltItem(i)

End If

i = i - 1

Loop

End If
```

I was going to let you figure it out yourself first, teaches people more. :[

[DopeyBiach]

Ahh, I always try and avoid looping, I never seem to get it right :L.. Thanks :]

[Joyce]

It's not hard, so long as you make sure to set a limit and actually GET to that limit it can't go wrong. 

[DopeyBiach]

Thanks for that, will keep it in mind.. My loops usually crash the prog.. And VB >_>

[Joyce]

That just means you're not closing and exiting them properly. :]
