As far as I know it will support any size as long as it fits in your VRAM.

The image is designed to fill the entire screen (so 1280x1024). How does the offset work? I have tried to use the "move at angle command". Is the offset designed to be used to fix some of the problems with that?

If you want a constantly scrolling background, you could set the offset to the Timer value. Like this:

+Always

-TiledBackground: Set image offset to Timer / 8, 0

Changing the value 8 will change the speed; lower numbers scroll faster while higher numbers scroll slowly. Also, dividing the Timer value by negative numbers will make it scroll in the opposite direction.

Now thank you indeed linkman,at last i really understand how simple it is!

Glad I could help.

While you wait for this to be fixed, there's a way to simplify the events by using a different expression:

+On Overlap between Player and Family[Behavior].VectorX

-Family[Behavior].VectorX = Family[Behavior].VectorX + ( Cos(Player.Angle) * 100 )

Haven't had a chance to test it, but I've done something similar before, and it should work.

Blah, sorry. That should actually be less than 100, not 0. Also, to fade in within half a second, change the code to this:

+If Object Opacity is Less than 100

-Set Object Opacity to Object.Opacity + 200 * TimeDelta

3)no matter how hard i try,i can't make OnScreen objects stay On Screen (like health bar,and stuff that i want to stay on screen while moving around. Hope you'll be able to help.

This right here is a use for layers. Create a new layer above the main one, place all of the objects you want to stay on the screen on to that layer(just drag them from the layout to the layer; it will keep them in the same spot, just move them to that layer), then set the "Scroll X Rate" and "Scroll Y Rate" values under the layer properties to 0. That will keep all of the objects you want in the same spot.

what about Gmax?

Is it still out there somewhere for download?

Yup, just have to get right here through TurboSquid. I honestly can't stand the program, though. Too many problems came from that tool while I was trying to mod Jedi Academy.

Under the System object there is an action to save/load save files called "Save/Load to disk". This basically takes a snapshot of the whole game, so everything is saved. I think the only way to alter them is using a HEX editor.

Instead of using the fade behavior, you could just do this:

+If Object Opacity is Less than 0

-Set Object Opacity to Object.Opacity + 100 * TimeDelta

You can change the 100 to anything you want, but that will make it fade in in exactly a second.

Wait a minute, I remember this kind of thing happening with someone else not to long ago. I'm pretty sure it has to do with VSYNC, particularly when the framerate drops below the refresh rate of your monitor. The framerate will half itself then.

Here's the topic where Ashley explains it.

It maintains a consistent 75 FPS for me.

Nice update. Good batch of bug fixes, and it's interesting to see how much VRAM my game is using. I did discover a couple of bugs, though, which are here, and here.
