The reason i put this in newcomers corner is because, well im a newcomer. i do not know what is wrong with my code! at first, i got it to make a red ball, then the camerawork was fine, but after putting the 'if then' commands, all i get is a black screen!

Ok, I'm kinda rushed but I took a quick look at it and here's what I noticed. The reason you got the black screen is because you forgot to put your sync in the main loop to refresh the screen. I've attached your code, but I modified it and remarked it so you could see what I did. It's not exactly what you had but its the same concept and if you study it enough it'll make good sense. I only made it move on the X axis but you could apply the same principle for the Y and Z axis. Click here--->
Hope this helps. If not I'll try to help more if I get the time if noone else has helped. BTW, sorry if it's confusing on what I did, I'm just not a very good teacher.

thank you smiley, and i added the if then for the y axis as well, but there is one problem, the ball does go up and down, but only one 'jump' or something
sync on
`added this for smoother faster refresh rate or sync rate
sync rate 60

make object sphere 1,1
color object 1,rgb(255,0,0)

`changed this section. Just moved it out of the loop. This will define your initial starting place.
position object 1,-5,0,0
position camera 0,10,-10

do

`just modified this. different than what you had but gives you an example.
IF rightkey()=1 then playerXpos#=playerXpos#+0.5
IF leftkey()=1 then playerXpos#=playerXpos#-0.5
IF upkey()=1 then playerypos#=playerXpos+0.5
IF downkey()=1 then playerypos#=playerXpos-0.5
`position object 1,-5,0,0
`position camera 0,10,-10

point camera 0,0,0

`added this to update your new object position each time the program loops
position object 1,playerXpos#, playerYpos#, playerZpos#

`forgot this. Thats why you had the black screen.
sync

loop

Ok, got you corrected here. Here's the modified code again. Take note of where I made changes. I left the old code that you put in there so you can compare the differences to mine to see what you did wrong.


Hope this helps.
