So how do you scale it if not in Obj mode, or whatever. I'm looking for more of an, "Scale: 1,1,1" or a "Scale: 100%" kind of way. Is there one of these in Blender?
I never said you can't/shouldn't scale in object mode. Only if you do you gotta do the cube fix for the model before exporting. No big deal.
New Protip added.
- To scale your mesh/parts of your mesh simply select it, press S on your keyboard and move your mouse. Alternatively you can type in numbers if you want more precise scaling. The scaling percentage can be seen in the bottom left of the 3D view.
 
How do I create and assign materials in Blender  2.54?
I switch back to 2.49 every time I want to add some color to my weapon
New Q&A.
Q: How do I add materials (color) to my mesh?
A: First things first. The only thing that matters is the material name. It doesn't matter what color it is, what sort of specularity it has or anything else. None of those will get exported, only the material name. So any color you add to your model in Blender is purely for Blender. I helps you with modeling, but that's all.
To add a new 
material to your mesh/part of your mesh select it, go to the 
Material tab in the toolbar on the right and click 
New. By default, it is named Material. Change it to your liking and your good to go for exporting.
If you want to have the color in Blender, then simply change the 
Diffuse color. If you do not understand RGB/HEX color system work, please Google it because that is something everyone using a computer should know. It's computer 101.
How do I get a hitting weapon working with a custom hitting in first-person?
New Q&A.
Q: My model isn't moving in first person in Blockland. Like swinging the sword. What to do? (Parenting meshes)
A: You need to have two 
empties in your model called 
Shape and 
Detail32. To add an 
empty press 
Shift + A on your keyboard and select 
empty. For some reason I have been unable to find the 
empty mesh from the 
Space menu. Do not move the empties, let them be in the center on the scene on top of each other. Once you have two 
empties, name one of them 
Shape by going to the toolbar on the right and clicking the 
Object tab. The name is in the topmost text box right of the orange cube icon. Now name the other one 
Detail32.
Now select all of your mesh, including 
armatures (I'll get to those later.), and parent them to 
Detail32. To 
parent one mesh to another, first you need to select the 
child mesh which in this case is your whole mesh. Then go to 
Object tab in the master toolbar and in the Relations tab there is a text box titled 
Parent. In this box type 
Detail32. Now your mesh (The 
child mesh) is parented to 
Detail32 (The 
parent mesh).
Once all of your mesh is parented to 
Detail32, select the 
Detail32 empty mesh and parent it to the 
Shape empty.
