SB4 supports multitouch? https://twitter.com/notohoho/status/1129515354181386241?s=09 TOUCH [touch ID [, coordinate system conversion flag]] OUT touch time, X, Y [, touch area] The reference gives this for touch, so I'm confused how multitouch would work. I probably read the tweet wrong...?
Something of interest is that the definition of a constant expression has been expanded, but it's a bit unclear. translated help page It seems like the functions CHR$ DEG RAD RGB are treated as constant expressions as long as their inputs are also constant expressions. So it's likely they are included in constant folding and are extremely efficient to use.
How does scaling different resolutions work? Does it just scale upwards with hard edges? Can we also expect significant performance variation between different resolutions?I go into some detail about screen scaling with XSCREEN and other aspects of SmileBASIC 4 in this guide, but basically:
- You can choose between bilinear filtering, nearest neighbor, or "smart nearest neighbor" which is apparently somewhere between the two, according to the reference.
- Probably the only real difference in performance would be graphics commands, since you'd naturally be drawing over a larger area of the GRP with larger resolutions. As for how big of a difference it actually is, we'll have to wait for the release to find out.
It cannot. The reason that was added to SB3 is because Miiverse went down and there was no longer any way to take screenshots. That's not the case on the Switch, which has a dedicated screenshot button. Either way, the SB3 screenshot function was pretty bad too in terms of JPEG compression, so it's not like we've lost anything.
I don't actually own a Switch yet, so I can't confirm, but I heard and read that the screenshots it produces are low quality and highly compressed. It's hard to capture pixel art type stuff with, well, any compression. I think it would be a little neat if SB4 had its own in-built function that could maybe snapshot the screen or whole GRPs or something. It would eat memory, which is probably why Nintendo chose to compress their system's screenshots so much, but that can't really be too big a hassle.
SmileBOOM just uploaded 4 videos on SB4. Now watch me try to analyze these. I probably missed a lot of stuff. The first video was https://www.youtube.com/watch?v=ayNsaxF5Kb4 it shows a Pi starter Mk II which seems to run SmileBASIC 4 based on the title of the video. The second video was https://www.youtube.com/watch?v=3ywNYBBqjN4 It's a simple autorunner but here's the thing, IT DOESN'T USE RETRO GRAPHICS! this means SB4 will have an option to use higher quality graphics! The third video was https://www.youtube.com/watch?v=hYqX0d2TsrM It's a version of solid gunner that plays with the switch turned 90 degrees. It also has 2P co-op and 3D CUBES. The background also seems to use multiple layers. The fourth and final video was https://www.youtube.com/watch?v=eTwqNyE1c54 It shows a part of the editor. According to the title of the video, it's an encoder. EDIT:They launched a 5th video. https://www.youtube.com/watch?v=HHDIQbS6CRw It shows the speed test in SB4. Not sure why they released it by itself but okay
