Ok well for my off-road motorcycle game i want it so when i go up hills, the bike rotates acourdingly to the slope angle so it is riding bothin wheels on the ground instead of plowing right through it (hehe i love these new smiles) but anyways, the line of code i am using is this : [b]if groundh#>posy# then xrotate object 1,(groundh#-posy#) (btw, im not sure of the ending formula, but it should be about right) now what happens is i hit the first hill and it adjusts to it then wont change anymore, because even in the loop, the rotate object command goes once then wont repet itself again. i tested it many ways, like the line if upkey()=1 then move object 1,1 repets over and over, but if upkey()=1 then xrotate object 1,10 wont work. any ideas? i cant think of a better way to fix it. thanks for the help

for sure it works but you don t see any changes because your command simply sets the xrotation angle to the value of groundh#-posy# (or 10 in the second example).
putting your command in other words what you are doing is:
if inkey$()=1 the set x angle to 10
to get an incremental thing you must code like this:
xangle#=object angle x(object)
if in key$()=1 then xangle#=wrapvalue(xangle#+1)

for the groundh# thing it would be:

xangle#=wrapvalue(xangle#+(groundh#-posy#))

(wrapvalue is used to make your angle stay in the 0-360 degrees range)

hope its clear..
cheers

P.S. > if groundh#>posy# then xrotate object 1,(groundh#-posy#) <
this is wrong since it will only react when groundh# is bigger than posy#, which may not be the case all the time

ooo wow thank you. i never realized that the xrotate object and such just set it, i thought it increased it. And i do have code to do it for downhill, i just didnt put it in. thanks to all for the help.
