Making Bitmap Expression update every frame?

myraneal · Post by **myraneal** » Tue May 13, 2008 8:03 am

Hey all,
Is such a thing possible, to update a Bitmap Expression component update every frame, so that the calculated bitmap changes according to other variables and such?
I wanted to do this for a "power bar" when shooting a ball kinda thing, and I solved my problem with another method, but I'd still like to know.

Thanks,
Yılmaz

Hi Yilmaz,

Use the RefreshContent component. However, keep in mind that updating ( large ) Bitmaps every frame can get quite heavy on your CPU. Always try to look for a solution using Material:TextureX/Y first.

Hey Kjell,
Thanks

I really wasn't aware of the RefreshContent component. That should work. My bitmap isn't that big 32*128. I'll check if this will decrease the framerate much.

Thanks again,
Yılmaz

Perhaps you could try out pixel Shaders

Should work very well and with no FPS loose

Unfortunately, I'm not familiar with shaders at all

If you could point me towards a tutorial to start from that'd be most appreciated.
