Load Blood Gulch since its a basic and popular map, so lets change the teleport location of the blue base, first of all, some ppl seem to think that just moving that little thing with the green glow comming out will work, it wont, its just scenery to make the game look good. So to change the Blue base telepot location go to the EDIT tab, select SCENERY, now click SELECT MODE(the little yelow arrow on the toolbar) click the thing i just told u about that u appear out of from the blue base teleport, in this case its the one nearest the fuelrod gun, move it to where u want to teleport by clicking TRANSLATE MODE while the thing is still selected, and clicking and holding it to drag it. Next click the EDIT tab again, select MP FLAGS, now go to where the thingy origonally was, you'll see a little box where it was, use SELECT MODE to select it, then use TRANSLATE MODE to move it under the thingy again, there, now u can teleport there from blue base, that little box thing is the reason u teleport, you'll see more of those things in the level but they have different uses, a circle is the HILL for King of the Hill.

Now to add a double link teleport, we wont attach the red and blue base because blue base has been altered, lets use the little cave on the side of the big cliff(not sniper perch), nearest blue base, now, go near that area, and then go to tools and click add teleporter pair, two boxes will appear, a little luck is involved here, cause there is no way to tell which one is the transporter, and which is the reciever, so move one into the cave, and one to where u want to teleport, unfortuanatly, SparkEdit cant move the telepoter shields (the green things on the bases) so u cant see the teleport area, but u can move the teleport pad, select a pad and click DUPLICATE SELECTION, under tools, now move the duplicate over ur reciever, then create another teleport pair, again luck is involved here, put one that might be the teleporter over the reciever, and put the new reciever over the other teleporter, u can now travel back and forth between those two teleports.

Now for Weapons. this is simple, select MP equipment under the edit tab, be aware that u dont choose Weapons, now select the weapon u want to be moved and move it, or if u want to keep it there but add it some where else on the map, duplicate it then move the duplicate.
For vehicles its the exact same only select Vehicles under edit and move the one u want to.

And lastly, spawning points, this can be a little annoying, select MP flags, then look for areas that u spawn in, thats the annoying part because the spawning points are boxes just like all the others(ie teleporter, hill), so find the area u want to spawn in and move the origonal spawn point, or dupicate it to add another.
