Updating from 1.7.2 to 1.7.10; Coding problems

Hey guys,

I'm trying to update a mod for entity rendering from 1.7.2 to 1.7.10. It works fine in normal Minecraft Forge 1.7.10, but when I put it into eclipse and try to run it in Forge 1.7.10 there, I get the following errors. Can someone help me?

entity.field_70155_l /= XYConfig.entityRenderRange;

error:

  - field_70155_l cannot be resolved or is not a field.

World world = Minecraft.func_71410_x().field_71441_e;

errors:

    - the method func_71410_x() is undefined for the type Minecraft

    - line breakpoint:CTH [line: 25] – onTick()

Iterator i = Minecraft.func_71410_x().field_71441_e.field_72996_f.iterator();

errors:

  - line breakpoint:CTH [line: 27] – onTick()
