I was going to start making a 2d tank game with dynamic terrain, similar to scorched earth. I'v almost got it working exactly how i want it, but i'm having a problem getting the terrain to fall down. Insted it just collects on the bottom and you can't see it fall. I want to know if it would be really complicated to get it to work the way i want or if im just making a stupid mistake.
Thanks.

ps.
make sure you are in fullscreen 640x480 true color not 16bit
click the mouse to create terrain

Never mind... i figured it out today, my vertical loop just had to count backwards insted of from 0. Stupid mistake! Anyway i included the source for a little snow program using memblocks I get a constant 31 fps on a 2.0ghz athlon with a geforce3. Test it out and see what you get. If you can find a way to make it run faster I'd like to know!

Nice work ... apart from the fact that I wouldn't have done it that way

I get 7fps on my laptop. With a few changes to get the syncing right (SYNC ON:SYNC RATE 0 at the top and change the final SYNC RATE 0 to just SYNC) I can boost that to 8fps.

However, if I remove that set of loops in the middle and replace them with a COPY MEMORY command, I boost the frame rate to 42fps

My laptop is an 850PIII BTW

Yeah your version definitly runs faster! I get 60 fps. Only, is there any way to get the snow to build up like i had before and still keep the high framerate? If there was that would be really cool! Thanks for your help.

IanM, is your version suppose to look like snow falling and not have the terrain stay at the bottom of the screen? 100fps with that.

Well, I obviously didn't leave it running long enough to see the whole effect ... let me think about it for a while and I'll see what I can come up with

I get high 70's dropping to low 70's on my laptop

Still, with a small optimisation, I can boost it into the mid-90's

With yet another, I can boost it to 106 constant

Stand back! Master of optimisation at work

make memblock from bitmap
make image from memblock
then texture the plane with that image

CTP

Lifes short, try to enjoy it and not take it to seriously!
