my computer is poop. it's very bad. i am having trouble with playback when i open the ram watch viewer, but not running lua scripts. my question is, what syntax is wrong here? Download test.lua
Language: lua
local ramAddress = 0x7E0577
local ramValue

while true do
  ramValue = memory.readbyte(ramAddresss)
  gui.text(0,0, ramValue)
  emu.frameadvance()
end
ultimately, i want to write a script that displays things like speed and position on the screen. this will circumvent playback issues.

You wrote ramAddresss with 3 s within the loop.

Also, from the looks of it, it seems you are attempting to read a SNES address. The address you have is from system bus, but memory is set to WRAM space by default. You either need to set the memory domain to the bus, or convert your address to WRAM. I think you chop off the 7E to convert from bus to WRAM? I'm not 100% sure of that though.
It's hard to look this good. My TAS projects

thanks for noticing the typo. the code works perfectly well with snes9xrr, but still throws an error on bizhawk :/ the current error is an infinite loop

As adelikat said, BizHawk defaults to WRAM region. You cannot use the bank $7E at the beginning of the address, unless you set the region to BUS, "System Bus" IIRC. 
Language: lua
local ramAddress = 0x0577  -- WRAM is from $00000 to $1FFFF for SNES
local ramValue
memory.usememorydomain("WRAM")  -- just in case

while true do
  ramValue = memory.readbyte(ramAddress)
  -- ramValue = mainmemory.readbyte(ramAddress)  -- is valid too, without using memory.usememorydomain
  gui.text(0, 0, ramValue)
  
  emu.frameadvance()
end

Tip: Is memory.readword or mainmemory.readword listed in the reference?

no, i looked at your references shortly after posting. im using memory.read_s16_le now. it works for 1 ram value but not for 2

This appears to be something you may want: memory.getmemorydomainlist

This means that "domain" is optional and will be set to null by default if you leave it out. In this case, you should be safe to just leave it out, because you set the domain earlier.

thx! btw, this is the code im using: Download this.lua
Language: lua
local front = 0x056F
local frontVal
local xDiddySpeed = 0x0E8D
local xDidSpdVal
local xDiddyPosition = 0x0B1D
local xDidPos
memory.usememorydomain("WRAM")  -- just in case

while true do
    frontVal = memory.readbyte(front)
	if (frontVal == 2) then
	    xDidSpdVal =  memory.read_s16_le(xDiddySpeed)
	    gui.text(0, 50, "Speed - "..xDidSpdVal)
		xDidPos = memory.read_s16_le(xDiddyPosition)
		gui.text(0, 65, "Position - "..xDidPos)
	end
  
    emu.frameadvance()
end
Why wont this work??

I don't have a ROM of DKC handy, so I can't tell what's wrong with the script. What is the script supposed to do, and what does it do instead?

well, it's supposed to display speed and position on screen. instead, it falls in an infinite loop of some sort. so something is obv wrong in my syntax/code

That's weird. Trying the script on another game displays the values fine for me. The game also runs normally. I don't know what's going wrong for you.

Try version 1.11.6. Sometimes bugs do sneak their way into these things.

Your script is working for me. Remember that it only displays that information if Diddy is the active character, not Donkey. Also, I would recommend using a colon instead of a dash to separate your text from your value, as speed goes negative when traveling left.
