Changing the hurt flash color/effect is currently not possible without modifying the engine.

it replacing the red flash effect with randomly colors

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_on_player_hpchange(function(player, hp_change)
   if hp_change<0 then

      local name=player:get_player_name()
      minetest.after(0, function(name,player)
         local r,g,b=screencolor.rndhexcolor(),screencolor.rndhexcolor(),screencolor.rndhexcolor()

         screencolor.user[name]=player:hud_add({
            hud_elem_type = "image",
            text ="screencolor_scr.png^[colorize:#" .. r .. g .. b .. "aa",
            name = "rndcsc",
            scale = {x=-100, y=-100},
            position = {x=0, y=0},
            alignment = {x=1, y=1},
         })

      end,name,player)
      minetest.after(0.8, function(name,player)
         player:hud_remove(screencolor.user[name])
         screencolor.user[name]=nil
      end,name,player)
   end

end)


screencolor={user={}}

--screencolor.user[name] then id is stored as a global var if you want to use it to somthing


function screencolor.rndhexcolor()
   local a="0123456789ABCDEF"
   local a1=math.random(1,16)
   local a2=math.random(1,16)
   return string.sub(a,a1,a1) .. string.sub(a,a2,a2)
end

[AiTechEye]

many things is possible in minetest, even people dont know it :-)

Yay!

For the positivism quotes!

A question, how to make exactly white?

I mean if you can setup what color turns the screen when you are in lava, how you can't do it with a tool?

[AiTechEye]

you can do it with everything that works with the code :-)

the screencolor.rndhexcolor() makes a random code (0 to F)

image.png^add_effect_or_image

How hex/colors works:
the last 6 numbers is replaced with letters
0.1.2.3.4.5.6.7.8.9.10.11.12.13.14.15
0.1.2.3.4.5.6.7.8.9..A..B...C...D..E..F

so 3E = 3*14

red,green,blue,alpha
NN.NN.NN.NN
......................red....green...blue....alpha
3EFFBCFF = 3*14, 15*15,11*12, 15*15
so FFFFFFFF = full,full,full,ful = 100% white
