Stef, thanks for the ballpark numbers. Miquel, my (very) tentative plan is a top-down RPG, so functionally there will only be maybe four or so tile types (non-solid, solid, water, and maybe one-way blocks? Not sure yet), but aesthetically several tiles per category (very rough order of magnitude, ma...

I have a rough map-loading strategy that works well enough (for my tests at least), I was just wondering roughly what kind of efficiency I might expect for rescomp's "IMAGE" structure. I understand that it will be map-dependant, but rough order of magnitude, are we talking 5-10%? 25-50%? 10-90%? My ...

So I'm experimenting with using very large scrolling maps. I've got a rough system in place to load the map on the fly as the player moves, but the problem I encountered is the limit of how large of a map can be unpacked to RAM (some trial & error testing put the approximate maximum at two maps (FG ...

No, I understand the palette structure. My mistake was assuming the "PAL1" used for the "pal" parameter of VDP_setPalette() was a full palette structure; I didn't realize PAL1 was just a defined constant (u16) 1. My experiment was going to be passing the "pal" parameter a value from a 2D array, wher...

Hah I see, this is a silly mistake on my part. I just spotted the constant definitions for "PAL1" (and the others) in vdp.h, so they're not actual palette structures that need a pointer. All I would need for this experiment is a u16 array of numbers 0-3. Thank you!

Hi, thanks for the reply! So I don't fully understand how SGDK handles the palettes (PAL0 thru PAL3), they seem to come pre-declared? Take the moon tutorial for example: #include "moon.h" int main( ) { // get the palette data of moon VDP_setPalette(PAL1, moon.palette->data); // load bitmap data of m...

So I don't end up flooding this forum with individual threads per question, I figured it'd be better to add them all to one general thread as I learn. I've been experimenting with different methods of loading the map on the fly as the player moves (for maps bigger than the VDP limit), and I had the ...

Ah, I see. Was a little confused why mixing types wasn't throwing a warning in the compiler. That makes sense, thanks

Should I not be using them? The only reason I ask is I've seen bool types used in other functions (TILE_ATTR_FULL, for instance).

Ah, thank you! The coordinates aren't as important (I was just curious), but for testing it's easier for my project to disable the background scrolling (plane B) to keep the FPS on screen.
Also on a side note, the "float_display" parameter should kind of be a bool instead of an int, shouldn't it?

Hello, I have a quick question about the VDP_showFPS command. Is there any way to make VDP_showFPS draw to plane B instead of A? Or to set the coordinates?

Thank you for your help.

Previous post deleted, I found the unpackMap command and have it working now. Thank you!

I understand IMAGE contains a tilemap, so what I'm trying to do is modify kcowolf's scrolling demo to use images instead of the hard-coded map/tiles. Looking at this example project, kcowolf passes an array (containing the tilemap) directly to a MAP structure, and then the rest of the code handles d...

Hello, I have another question about rescomp. The list of structures says that maps are not yet supported: https://github.com/Stephane-D/SGDK/blob/master/bin/rescomp.txt MAP --- NOT YET SUPPORTED ! Take an map file as input and transform it in SGDK Map structure. Map is used to define background pla...

Ah, rookie mistake, trying to do math with dissimilar variable types. Obvious in hindsight! Just need to get used to the new int/float types, thank you!
