I am creating a simple project where you can walk around a room and talk to people. I have asipmple function that handles all the text on the screen. The problem is that as soon as i put the text on the screen it disspears as soon program moves to the next line of code. I have tried a wait command but the text still disspears. I am sorry but i do not have a code snipnett because it is on a different computer not hooked up to the internet. All i need is the code to stay on screen till I tell it to clear. Thanks

run your sync manualy

sync on:sync rate 0

then draw all the 3d in your loop, then right before the sync that gets the screen drawn display the text, eg:

for I=1 to 50
position object I,x,y,z
next I
text 200,200,"this won`t get overwritten!"
sync

then redo the loop, you have to draw the text before every sync, just displaying it in a subroutine and then expecting it to remain won`t work, cheers (example code below, click the source button)

if you want to do a wait command all you have to do is switch the backdrop off when you want the text to appear and switch it back on when you want the text to disappear.

Or you could put the text command before and after the sync command or turn "DRAW TO FRONT". If you turn backdrop off in 3D, you get a smudge affect that occurs everytime the object moves.

Everytime i want text in a 3D game, I use the 'set camera viewport' command to set some space aside for the text (or 2d drawn huds) either at the side or the top of the screen. When the sync command is used, or when the 3D screen changes, the section outside the 3D area will not be affected, so the text will not disappear.
