Alternate color! http://gocha.is.land.to/down/public/smwdb-2p.png Thanks pirohiko for processing it :p
Someone please make me a rewind script similar to this for Snes9x, that can be toggled by using a hotkey (eg: Ctrl), or a joypad combination (say, L+R+select). thanks in advance and keep up the great work, but please provide some sample scripts in the next release, haha. :)
hotkeypad = joypad.get(5)
if hotkeypad["X"] then doRewind() end
That script looks not only useful, but also stylish! Thanks for making and publishing it! I had a look at the source code, and I have a few comments: * There is a lot of code duplication. Generally, when you find yourself wanting to make variables with names foo1, foo2, foo3, ..., that is an indication that you really want foo to be an array instead. That way you can loop instead of repeating code.
* The weapon ammo formulas were extremely complicated! I tried rewriting them using arrays and loops, but the formulas were too different. Are you sure those memory addresses are the easiest way of getting at the ammo?
* You said that the hitboxes were approximate? In what way are they approximate? Looking at your picture, they seem to have the right size and shape, but their location seems to be a bit off. Perhaps you are adding a Y value instead of subtracting it? It looks like the hitboxes for the bats would work better if they were flipped horizontally around their top. If that is not the case, perhaps you can look around at nearby memory addresses - they might contain extra information you need to make sense of the hitboxes.

If you could walk me through the process, i'd be entirely grateful. Or even if you could tell me how to install the library. Thanks.
require "gd"Amaurea, I really wanted to use your animated ghost script for Super Metroid to practice speedrunning against one of my runs. I was able to get the old version to work, but this new version (requiring the Lua GD Library) is beyond my area of knowledge.
Mouse input support (as in, synthesize events for the snes's mouse input device). Yes, no? I cannot find any mention of it in the documentation. I am thinking of Mario Paint. It's been four years since this topic was brought up. Has there been any progress?
assert(joypad.gettype and joypad.gettype(1) == 'mouse', "You must be running Snes9x 1.51 with mouse enabled in port 1.")
while true do
-- move the mouse in a circle at an arbitrary speed
local xpos = 128 + 64*math.cos(emu.framecount()*0.125)
local ypos = 128 + 64*math.sin(emu.framecount()*0.125)
joypad.set(1,{x=xpos,y=ypos})
-- hold left click except on every 64th frame
if AND(63,emu.framecount())~=0 then
joypad.set(1,{left=true})
end
emu.frameadvance()
end
One important caveat not shown by the above demo: the mouse movement is completely relative, although Snes9x both provides and expects the mouse input position in "unbounded" absolute coordinates. Only the game knows where the cursor is really positioned, so if you want to put it at a certain logical position you'll have to move it relative to the value the game has stored for it but represent it relative to the emulator's coordinates. So, here's an example of how to move the cursor to the middle of the screen in Mario Paint:
local cur_game_x,cur_game_y = memory.readwordsigned(0x7e04dc), memory.readwordsigned(0x7e04de) -- where the game thinks the cursor is
local cur_virt_x,cur_virt_y = joypad.get(1).x, joypad.get(1).y -- where the emulator thinks the cursor is
local new_game_x,new_game_y = 128, 112 -- where we want to put the cursor onscreen (the middle of the screen)
local new_virt_x,new_virt_y = cur_virt_x+new_game_x-cur_game_x, cur_virt_y+new_game_y-cur_game_y -- final input to emulator
joypad.set(1,{x=new_virt_x, y=new_virt_y})
Also, although this issue isn't specific to Lua scripting, keep in mind that the game usually imposes some limit on how far the cursor can actually move in a frame (such as at most +/- 128 pixels on each axis per frame, or 0 pixels if the game is busy thinking).
