Whenever I render, it doesn't show the texture I make GFX on a game called Roblox, and today I was making one but when I rendered it, the render didn't have the texture on it. It still has the texture on it in 3D View though. Please help because I cannot find a solution anywhere online and I have tried most things and it still doesn't have the texture on in the render, even though it does it 3D View.
Assuming your texture is an image file this should work.

Change it from Blender Render to Cycles Render. Go into edit mode(tab-key) and unwrap it(u-key). Go into the node editor. In the node editor bring up the node add menu (shift + a), and select image texture. Assign your image/texture to the image texture box. Attach the yellow node from the texture image box to the diffuse box.. This should work.
