I wrote a function that shows the mouse coordinates and sprite number of the map tile you are hovering over. I originally wrote this for myself to make checking the tiles on my map easier but figured I could share it in case anyone else finds it useful.
function debug_mouse()
local mx,my = mouse()
local x_offset=5
local y_offset=5
--window width and height
local w=480
local h=270
--offset if box leaves screen
if mx>w-20 then x_offset=-15 end
if my>h-29 then y_offset=-24 end
--draw debug text box
rectfill(mx+x_offset-1,my+y_offset-1,mx+x_offset+14,my+y_offset+23,1)
print(mx,mx+x_offset,my+y_offset,8)
print(my,mx+x_offset,my+y_offset+8,9)
print(mget(mx,my),mx+x_offset,my+y_offset+8*2,10)
end |
Thank you for the script, however it wasn't working correctly because it looks like coords for mget work off cell coords rather than pixels, I modified the script to correct that and also add flag output
function debug_mouse()
local mx,my = mouse()
local x_offset = 5
local y_offset = 5
-- tile size
local tw=16
local th=16
-- window width and height
local w=480
local h=270
-- offset if box leaves screen
if mx>w-20 then x_offset=-15 end
if my>h-29 then y_offset=-24 end
-- draw debug text box
local tile_x = mx/tw
local tile_y = my/th
local sprite = mget(tile_x,tile_y)
local flag = fget(sprite)
rectfill(mx+x_offset-1,my+y_offset-1,mx+x_offset+14,my+y_offset+23+8,1)
print(mx/tw,mx+x_offset,my+y_offset,8)
print(my/th,mx+x_offset,my+y_offset+8,9)
print(sprite,mx+x_offset,my+y_offset+8*2,10)
print(flag,mx+x_offset,my+y_offset+8+8*2,10)
end |
have you found out how to round the coordinates to integer? I've been trying to use the flr() function but it's still showing the decimal part
@MaddoScientisto as you see mget should function with non-integers. If you still want to round flr seems to work fine in my tests.
print(flr(mx/tw),mx+x_offset,my+y_offset,8) |
The other option is to use the floor division operator //
print(mx//tw,mx+x_offset,my+y_offset,8) |
@instring thank you, yes it did work but I wanted to format the output string without the decimals, in the end I found out that using the integer division operator "\" works as well, plus I learned how to use string.format so here's the updated code:
function debug_mouse()
local mx,my = mouse()
local x_offset = 5
local y_offset = 5
-- tile size
local tw=16
local th=16
-- window width and height
local w=480
local h=270
-- offset if box leaves screen
if mx>w-20 then x_offset=-15 end
if my>h-29 then y_offset=-24 end
-- draw debug text box
local tile_x = mx\tw
local tile_y = my\th
local sprite = mget(tile_x,tile_y)
local flag = fget(sprite)
rect((tile_x*tw)+tw,(tile_y*th)+th,tile_x*tw,(tile_y*th),8)
rectfill(mx+x_offset-1,my+y_offset-1,mx+x_offset+14,my+y_offset+23+8,1)
print(string.format("%d (%d)",tile_x,mx),mx+x_offset,my+y_offset,8)
print(string.format("%d (%d)",tile_y,my),mx+x_offset,my+y_offset+8,9)
print(sprite,mx+x_offset,my+y_offset+8*2,10)
print(flag,mx+x_offset,my+y_offset+8+8*2,10)
end |
As a bonus I even added a square around the affected tile, I only didn't bother changing the size of the coords box
@369369369 I would put the call to it at the end of your draw function. The actual function definitition can go anywhere in the file.
function _draw()
cls()
map()
debug_mouse()
end |
If you haven't already make a few test sprites and make a sample map. It doesn't have to be fancy, just so you have something appear on screen when map() is called.
This is nice! Here's my version with some edits:
- works with games that use camera()
- works with games that use different vid() modes
- text will always stay onscreen
- more descriptive text
function debug_mouse()
-- tile size
local tw,th = 16,16
local mx,my = mouse()
local cam_x,cam_y = camera() --reset temporarily
-- find window size
local scrw,scrh = 480,270
local video_mode = @0x547c
if (video_mode==3) scrw\=2 scrh\=2
if (video_mode==4) scrw\=3 scrh\=3
-- gather tile info
local tx = (mx+cam_x)\tw
local ty = (my+cam_y)\th
local tile = mget(tx,ty) or 0
local flags = fget(tile)
-- highlight tile
camera(cam_x,cam_y)
rect(tx*tw-1,ty*th-1,tx*tw+tw,ty*th+th,7)
camera()
-- draw mousemap info
local text =
--string.format("\#1mouse():%d,%d",mx,my).."\n"..
string.format("\#1mget(%d,%d):%d",tx,ty,tile).."\n"..
string.format("\#1fget(%d):%d",tile,flags)
local textw,texth = print(text,0,10000) --measure
texth -= 10000
-- clamp onscreen
local x = mid(0,scrw-1-textw, mx+4)
local y = mid(0,scrh-1-texth, my+4)
print(text,x,y,13) --draw
-- restore camera
camera(cam_x,cam_y)
end |
