Hy, is there any way around necessary Base Class edits?

depends, sometimes you jsut dont knwo of a certain forge feature that you can use, some other time you would really have to make a base change if you wanted to implements what you have in mind

 

 

what do you need to do ?

The player only should be able to do certain things(like using a chest/ having an air bar underwater) under certain conditions

jeez, the subject is very large

 

certain thing under certain condition

 

for using a chest you can always use the PlayerInterractEvent with Action of right blick block

for the rest it really depends, its mostly gonna be case by case

ok, but in general there is no way around it? I heard something about AccessTransformers, but I don't realy know what they are, if there are able to help me and how to use them

access transformer are only to change the visibility of field/methods

ASM can change vanilla code at runtime (like when you launch the game)

so basicly its like making vanilla changes, but youre doing vanilla change using code

 

baiscly its code changing code yes

so i could technicly hook into a void where for example health-=5; is called and put it into an if statement?

Yes you can, you can do a lot of these things.

 

How is your skill with java, if it it's above beginner you may be able to understand and utilize ASM properly to achieve this.

But don't fool yourself, if you aren't steady in the basics, this wont just be hard it will be frustrating and insanely difficult to do right

I think my java skills are pretty ok, so i shoul be able to do it

ASM could hit you like a truck in the face btw, watchout

I sign this, I'd recommend that you try playing around with ASM in a new mod, where you just try to edit simple things as first, try to edit how a simple TnT explosion work by editing the range or something else simple.

 

And start from there

also, when you looking in the source for what you want to change, when you find it make sure you unsdertadn everything if whats going on from main(String[]) to the method you want to change, sometimes you will change something and realise its not even what you wanted
