  NextBuild sprites
Posted by: Crivens999 - 11-13-2023, 10:08 AM - Forum: Help & Support - Replies (2)

Been using NextBuild for a little while, mucking around with my own editor for creating maps/sprs etc, got my scrolling tilemap working, but have hit a bit of a wall with sprites.
Ok so as far as I can gather the Next can handle 64 hardware sprites with 256 colours, or 128 hardware sprites with 16 colours (4bit).

When I use the InitSprites command I think this loads in upto 64 (or 128 for 4bit) sprites into the video memory (max is 16k). Then when I use UpdateSprite I can assign one of those sprite images (patterns in code) to a sprite ID. So I can use the same sprite image many times for my 64 onscreen sprites.

All good, except my main player is 4 sprites (32x32). It can move in 8 directions, and there are 5 animation frames. So in total 160 sprites just for the player.

So I'm running out of sprites. Now before I go mucking around reducing graphics to single sprite sizes, or using flipping/mirroring etc, then is it possible to use InitSprites, or some other command, to force load new images over the loaded ones? I was thinking of keeping the first 4 sprites just for the player and then just initialising those 4 sprites as the animation or direction changes. A quick test of using InitSprites (for the full 64 sprites) every frame shows this doesn't slow things down badly, so hopefully is possible. I don't really know ASM well enough to alter the InitSprites, but basically would be the same but with a starting point (so can init just the first 4 sprite, then the next 4 sprites (eg. for enemy)). 

Also is it possible to use 8bit graphics (256 colour) for the layer 2 tilemap, and 4bit graphics (16 colour) for the sprites?

  Where is the return value? (solved but with exit error)

LET s$ = "1+1"
LET s$ = CHR$(_VAL) + """" + s$ + """"
LET r = EvalBasic(s$)

How do I get the return value of VAL ?

  Microdrive or +3 Disk support when saving & loading
Posted by: jonesypeter - 08-10-2023, 05:40 PM - Forum: Help & Support - Replies (2)

Hi,

I'm creating an application with lots of arrays and wondered if the save and load commands support the microdrive syntax, or saving to +3 Disk?

Many thanks

Peter
