I was able to console verify this up until what appears to be the very last frame, at which point Mario's final throw appears to miss and instead Mario meets his demise between two of Bowser's mechanical minions.
Pi is defined as the ratio between the circumference and the diameter of a circle. This ratio is constant, regardless of the diameter. Everybody kind of takes this for granted, just because they say it is. But this got me thinking how exactly could one prove that the ratio is constant? This doesn't seem to be trivial to prove. It doesn't even seem trivial to see intuitively.
noob question: how do I set a path for lsnes?
However, the functions that use the native surface (all but gui.text) don't care about the screen size, but about the buffer size: client.bufferheight() and client.bufferwidth(). You should probably be aware of those two issues[1, 2], that were only fixed after the latest release.Language: luawhile true do local height =client.screenheight() gui.text(10, 40, height) emu.frameadvance() end
In general, you don't need to click on the 1st five options. Save prefix is handy, because you don't mix the states of this movie with others, even if you use the same slot.
To use many controllers, without a bunch of hotkeys, use Tool > Edit Movie or my Lua script.
To set: uint32 bit.set(uint num, int pos) Sets the bit 'pos' in 'num' Edit: typoLanguage: luavalue = 0x96 -- 10010110 for bitnum = 0, 7 do if bit.check(value, bitnum) then some_action() end end
E: So, the upshot is now I'm going to be requesting a new joypad function: joypad.countPlayers(). Should just return the number of controllers the core will accept inputs for at that time - example, if in N64 mode you have it set up for three controllers, joypad.countPlayers() should return 3.
EDIT: it doesn't count possible unconnected controllers.Language: luafunction joypad.countPlayers() -- returns the highest argument joypad.get(arg) can have / or nil if arg == 1 returns nil or an empty table local next = next local MAX = 100 for count = 1, MAX do local joyget = joypad.get(count) if (joyget == nil or next(joyget) == nil) then if count == 1 then return nil else return count - 1 end end count = count + 1 if count == MAX then error"joypad.countPlayers: something went wrong" end -- sanity check end end
Language: luaclient.SetGameExtraPadding(32, 32, 64, 32) event.onexit(function() client.SetGameExtraPadding(0, 0, 0, 0) end) while true do -- default SNES NTSC emu space: 256x224 gui.drawRectangle(0, 0, 600, 500, 0xffff0000, 0xa00000ff) gui.drawText(256, 224, "TEST") emu.frameadvance() end
Further development would be better in the Oddysee thread.Language: lualocal abe_semi_width, abe_semi_height = 8, 24 while true do local abe_x = mainmemory.read_u16_le(0x1f6112) local abe_y = mainmemory.read_u16_le(0x1f6116) local camera_x = mainmemory.read_u16_le(0x08abe6) local camera_y = mainmemory.read_u16_le(0x08abea) local x_offset = 203 + abe_x - camera_x local y_offset = 124 + abe_y - camera_y gui.text(0, 64, string.format("Abe (%d, %d)", abe_x, abe_y), "black", "yellow") gui.text(0, 80, string.format("Cam (%d %d)", abe_x - camera_x, abe_y - camera_y), "black", "yellow") gui.drawRectangle(x_offset - abe_semi_width, y_offset - 2*abe_semi_height, 2*abe_semi_width, 2*abe_semi_height, "blue") gui.drawPixel(x_offset, y_offset) emu.frameadvance() end
Right now, I'm curious to find out why it sends multiple button presses - it's currently sending two buttons with each update. My current guess is because the key state table (keysArray) isn't actually getting reset between calls.
Language: luaevent.unregisterbyname("some-fancy-name-onframestart") -- deletes the first registered function with this name event.onframestart(core, "some-fancy-name-onframestart") -- registers core, on frame start, with this name
Edit: typos / HTML code screwing.Language: lualocal x = marioX + dx + 8 --> gets the relevant X, that is around Mario local y = marioY + dy - 16 --> relevant Y local page = math.floor(x/256)%2 --> x//256 is the screen number, so page is the screen parity local subx = math.floor((x%256)/16) --> horizontal tile (each 16 pixels) local suby = math.floor((y - 32)/16) --> vertical tile (each 16 pixels) local addr = 0x500 + page*13*16+suby*16+subx --> bijection between the pair (subx, suby) and the address it is stored, with offset $0500 if suby >= 13 or suby < 0 then --> ignore tiles far away return 0 end if memory.readbyte(addr) ~= 0 then --> the memory is non-zero iff there's a tile there. It treats all different tiles equally. return 1 else return 0 end
