Minecraft Forums

you must include the prefix then the option you want followed by the suffix. It is not completely clear. It just lists the prefix and suffix but says nothing about them being required.

Quote from Ricowan

True, and maybe maybe your post will help others who are struggling with English... But that's what the words "prefix" and "suffix" mean.

Thanks for being so condescending. Welcome to trolldom jerk.

I just downloaded the update for Rei's Minimap and noticed there were two .INFO files that were not in the previous version. Can anyone tell me if these .INFO files have to be copy and pasted into the minecraft.jar folder?

Yup. Still good though

I think yo u should add this to the minimap when ever you want to but i think you should make it so you can put a button to delete all the way points that you have put..

I was just wondering how the Cavemapping works, cause I can never see anything but a dark green screen with just slighty lighter green tunnels.

私はレイを愛して。

It would be awesome if you had to have a compass and map in your inventory for the minimap and large map to be displayed.

Rei's Minimap v3.2_04 for Minecraft 1.2.5
-Added: configuration of the "Preloaded Chunks" (This setting was always enabled in v3.2 ~ v3.2_03)
If enabled, you might get a bug

If you enable the "Preloaded Chunks" is the same bug may appear.

I just downloaded the update for Rei's Minimap and noticed there were two .INFO files that were not in the previous version. Can anyone tell me if these .INFO files have to be copy and pasted into the minecraft.jar folder?

.info files if mod information file for ForgeModLoader.
there is no problem without having to copy and paste to minecraft.jar

Every time I start the game, log into a server and Click C, the game turns into a blue screen for a moment before turning black and these errors are what I can find in the text log book. What might the issue be?

fixed in v3.2_02?

Would it be ok if i used this mod in a modpack?

What this direly needs is the entity viewer for multiplayer and opacity/size options for the entity blips.
