Apply a texture to an object

I made an object in blender.....When i put it in game ..it is black (no texture)
Just want to know is there a simple way to put a texture in it?

 

Look where and how is the texture unwrapped in Blender! Probably your texture is not unwrapped in the correct zone of the texture picture.

 

still a bit confused

 

Did you have unwrapped the object's UV you made in blender?

 

uh ,I used to do that once......

 

i have a problem with this, when i click in blender to make a uv project, this happens:

Anyone knows why?

 

Hi, you must select the edges that make the shape, the contour of the part of your object you want uv, and mark the seam. Repeat to make more parts in your object. After you can select only the faces inside the seam and unwrap a specific part of your object with the correct aspect of uv map.

1/Mark seam, contour
2/select area, click one face and ctrl-l, if seam is correct you must have only area inside seam.
3/unwrap

 

OK, i will try it tomorrow!, because i need to study for a math test now.
