are you 2d or 3d?

if you are using 2d you can use the play sprite command.
I'm assuming you have a tile sheet with 16 frames.
I don't have dark basic in front of me right now but I think the
syntax is something like

create animated sprite 1, "explosion.bmp", 16,1,1
play sprite 1, 1, 16, 1

if you are 3d and trying to texture a plain with your explosion you could check the face demo that came with your install look at the fire part. I believe they run an animation on a plain in that example.

ok the 2d explosion was easy ( I used a 4x4 tilesheet)


but man your right running an animation on a plain is tough
I can get the first frame of the tilesheet to show up with



but I can't figure out how to move over to the next frame I thought I just needed a nested loop where I incremented by .25 since it is
a 4x4 tilesheet but that dog don't hunt.
scale object texture 1, .50, .25
scale object texture 1, .75, .25
scale object texture 1, 1, .25

I checked out the face demo but the way they did it was to chop up the tilesheet into ( in our case 16 seperate images) that seems like cheating

has anybody run an animation on a plain using a single tilesheet?
if so I'd love to know how to do it.

I think you've inspired me to do something ridiculous and over the top, but ah well.

I've written a small library of functions to help put tilesheet animations on planes. I'll paste the code below, but I've also attached the source file itself. I recommend including the file into whatever project you intend to use it in as opposed to copying and pasting it below your main source file code.



And so, with this library, you can now do something like this:



There's a description of all of the commands in the library in the comments at the top of the source file.

I hope this is useful to someone.

oops sorry I meant kira

by the way completely off subject and has no reason to be included in this board (flame on me if you feel it necessary) but driving in to work there is this security guard at the front gate and he has the best beard ever! It has all these highlights, perfectly groomed...full yet not to thick I of course refer to him as super beard.

Of course now I have got to make a video game where super beard the security guard protects truth justice and the american way from all evil doers that would dare enter the front gate without authorization.

Awesome. I'm sure beatification will look good on a resume or something.

Glad you liked my library and I look forward to the adventures of Super Beard.

ok I'm working on a game for the kids in my sunday school class.
it has to be done in two weeks but I'm pretty close. Anyway I added Kira's library and animation on plains to it.

by the way there is a kid in the sunday school we call corn dog hence the references. I didn't finish the game I need to tie in some questions about the subject they are covering and I didn't make an end for it yet but I thought you might want to see the explosion animations on the plain when you hit a landmine.

it is kind of a slalom game just drive the truck with through with the arrow keys, go through the slalom (boxes) the arrow above the truck should tell you where the next one is and avoid the land mines.
