Yes, yes it can. PROOF I've tried it with TooManyItems
Single player commands are needed.
It does. It should work with a lot of other mods as well.
By using single player commands. being OP on a server OR by placing a mob spawner, achievable through mods/mcedit.
You need to make sure you delete the Meta-Inf folder. Some mods are not compatible with other mods. This happens when both mods have modifications to the same .class file. There should usually be a list of incompatible mods in the official forum post. If not, disable your mods one by one to determine which ones are not compatible, then report the issue to the developer of those incompatible mods. Another reason is because some mods must be installed in a specific order. For example, if you want to use "Too Many Items", "Single Player Commands" and "Zombes Modpack", the three most popular mods, they have to be installed in this order: - Zombes Modpack - Too Many Items - Single Player Commands Usually the developers will let you know if mods must be installed in a specific order to not crash.
too many items,single player commands,all mo's mods.
You can't make a "single player just for mods." All of your data is stored in the exactly same place and mods affect every single world. If it is a mod you can turn off then there is your answer.
WorldEdit
In single player you cannot open the chat box without mods. In multiplayer you press 'T'.
Minecraft actually doesn't support fire (used to make chainmail armor) as obtainable in survival, although mods like Single Player Commands, and Too Many Items can be used, although they are means of cheating.
You can't really cheat, but there are some mods (specifically, Single Player Commands and Too Many Items) that let you give yourself items. There are also inventory editors that let you edit your inventory and give yourself items.
Delete the bin folder in the .minecraft folder, start Minecraft, and it will say that it's updating. Let it update, then install all of the mods over again, but don't install the one(s) that you don't want.
Don't do that! You could get banned from the server as most servers dislike mods. Just be on the safe side and only use it in single-player
