Hey guys,

Is there any drawback to pasting the same sprite over and over in different coordinates on the screen, or should I use a separate sprite object for every location?

In my game I want the same wall sprite several times over on the screen and I'm thinking of doing something like this:

pseudo-code
{
paste sprite sprWall01, 0, 0
paste sprite sprWall01, 100, 0
paste sprite sprWall01, 0, 100
paste sprite sprWall01, 100, 100
etc.
}

I'm afraid that maybe it may limit me in the future. Do you think it will be faster on older computers or slower if I use a separate sprite object for each wall tile location? For ex:

pseudo-code
{
paste sprite sprWall01, 0, 0
paste sprite sprWall02, 100, 0
paste sprite sprWall03, 0, 100
paste sprite sprWall04, 100, 100
etc.
}

I dont see a problem with it. In essence it should save texture memory or image memory or location handling memory. affecting a wall tho with say a splatter will affect them all since they are all inherited from the one media location.

just realize that paste sprite is not a sprite, it is only the image the sprite uses, so knowing this, sprite collsion will not work with paste sprite. If you need the use the sprite collision commands you'll have to use multiple sprite commands to place them.

RGT may be gone but the best DBP forum is still alive and kicking, check it out.

Thanks for the tips, guys. My 2D level editor is getting along great now with simply pasting the sprites over and over again. There's no hitch in the speed or anything. Since my game is tile-based, collision can be worked out from my 2-dimensional array instead of using the built in sprite collision.

I've also figured out a cool way to simulate a 3D camera using offsets for movement and scaling the entire screen for zooming in and out! As I only have experience with 3D games, this 2D stuff is surprisingly fun and almost, dare I say it, better

If you arn't using sprites for collision or any of the sprite appearance commands you could use PASTE IMAGE instead and not have any sprites.

In dbpro sprites are 3d so when you create a sprite all the 3d stuff is started, it might load fractionally quicker without sprites and might result in a smaller exe. Proberly not worth the effort of changeing the code over though.

Are you serious? I wanted to avoid 3D so this game would run smoothly on my laptop. Hmmm... well, I'm using scaling and rotating of my sprites, so I don't think that's supported with images.

Thanks for the tip, though, I'll have to remember it for next time

its the way direct x 8+ handles all 2d stuff as a 3d billboard of sorts.

dbp has a demo using memblocks that pastes the same sprite like a 1000 times.

Hmmm I'll check the demo out. My engine needs to track and refresh every sprite individually because I'm emulating a 3D camera with rotating, zooming, and panning. Anyways, it works now, so the question was answered

I have a question : How are you changing panning, zooming, etc, in your game? I am trying to figure out how to do similar things, since I am making a 360-direction scrolling game.

no, seriously; I don't know how to do this. The manuals and command lists don't really tell me very much here
