messing around with the playdate again

an outline of a thick winding 2D path is drawn on a playdate screen. a black vision-cone rotates around, getting blocked by the path as it turns

@2DArray raycasting floor?

@2DArray parametric intersection ? to avoid the blocky look of mode7 textures?

@2DArray unrelated question : how did you get a video not destroyed by Mastodon compression ??

@2DArray perfect trajectory type of game? trackmania-like?

@2DArray did you get anywhere with SIMD rasterization?

fsouchu,
@fsouchu@mastodon.gamedev.place avatar

@2DArray 32 bits at once is what I do also - see the 3d sample in the SDK for a solid "fill line" starting point

@2DArray huโ€ฆ that would assume perfect frame alignement between runs

@fsouchu@mastodon.gamedev.place avatar

@2DArray I suspect you have no lua? cause I find my game to be highly unpredictable in term of perf (eg not a flat line for a static scene)

@2DArray this is not blue noised dithered, I am shocked ๐Ÿ˜ฑ

@2DArray I guess shadow on wall is doable no? are you drawing walls pixel row by pixel row?

fsouchu,
@fsouchu@mastodon.gamedev.place avatar

@2DArray render car shadow to a buffer (projected on floor) and sample rows if wall lands on a shadow pixel?

fsouchu,
@fsouchu@mastodon.gamedev.place avatar

@2DArray I mean - copy the row portion thatโ€™s left or right from wall pixel as a vertical slice

@2DArray excellent ๐Ÿ‘Œ

@Liquidream I first ran Quake on a P90 - I still see myself recovering my jaws on the floor ๐Ÿคฃ

@fsouchu@mastodon.gamedev.place avatar

@zep can you contemplate adding mouse lock? any fps work (quake or other) is a bit of pain right now!

fsouchu,
@fsouchu@mastodon.gamedev.place avatar

@Felice I suspect that's going to be trade-off - but a bit sad to use as an overpowered

WIP backups / file versioning for : all disk writes are (optionally) logged and earlier versions can be fetched by sticking a timestamp on the end:

> cat foo.txt@-30
-- shows foo.txt as it was stored on disk 30 seconds ago

@zep disabled by mount points? (eg not needed when saved on host OS)

@zep what is the planned memory envelope for a app?
the doc mentions โ€˜16mbโ€™ but unclear if thatโ€™s mappable memory and/or lua memory space.
(asking cause alpha is not enforcing any limit
afaik)

fsouchu,
@fsouchu@mastodon.gamedev.place avatar

@zep fine with that if fetch can support seekable/partial reads - as of now, it loads everything in lua ram
