|
|
[1:59:35][@Jim0_o][In the compression code there is an assert(LiteralCount == 0) it seems to fire on some files, should the literal buffer be flushed after the loop in case it didn't end on a run?]

|
[2:00:55][simple_compressor.cpp: Enable RLECompress() and LZCompress() to correctly flush the literal buffer]

|
|
[2:03:06][@thesizik][Are you going to consider resizing the debug display for lower display resolutions, or would that not really be worthwhile since it's not part of the final game?]
|
||
|
|
[2:07:50][@phillip_green][A wee bit off-topic, but have you ever considered setting up a green screen / chromakey for your stream?]
|
||
|
|
[2:08:49][@tukimitzoo][What are your 2017 resolutions for Handmade Hero?]

||
|
|
[2:09:22][@mtsmox][Shouldn't the cliprect only be rescaled at the same point that the offset is done? Only the main buffer should have it]
