Slow scrolling?

[Jarzka]

Hello.

My game has lots of water objects. I can not paste them to background because I want to hear some sounds when the player walks over it. There are about 2000 objects in the level.

But when I use scrolling (center area to the player) the FPS is about 5. If I don't use scrolling fps is 50. Why?

EDIT: And with HWA beta FPS is 15.

If they are not animated you can use backdrops with an invisible active generating sounds on top of them. If the screen is not scrolling mmf doesn't have to redraw the actives, that's probably why it is not lagging.

I tried it already and fps is about 1-5. I can not understand because MMF doesn't have to draw invisible objects (only the geometry) and still it's slow? ALSO with HWA.

Bad code?

Try directx + Vram.

DirectX + Vram is always slower than Standard (at least on my computer).

can you send us the file?

Also, are they actives or backdrops? IF actives, theres some combo box in the actives properties (I forgot the name of the combo box) but the properties are: Yes, automatic and No.

Make sure it's on Yes.

Also there are some frame properties you can change to make it faster.

Scrolling seems to be a big problem...

EDIT: Well, making the water "inactive if too far away" it works but I don't know yet if it might cause some problems in the future. But thanks for help.

You could reduce the number of water objects by increasing their size. And maybe by placing them so they only surround water zones.

Maybe you can "code" the water:
X("Player")<10 And X("Player")>10 -> Do something
