(Solved)How do I overwrite array strings?

[zutokaza]

Basically the sol.surface font text is equal to test for displaying words test1,2,3,4, etc. I am trying to overwrite the first 0-7 tests.

Code ( lua) Select Expand

local test = {}
local testing

test[0] = "test1"
test[1] = "test2"
test[2] = "test3"
test[3] = "test4"
test[4] = "test5"
test[5] = "test6"
test[6] = "test7"
test[7] = "test8"

for i = 0,7 do
     show_test[rep] = sol.text_surface.create({
      text = test[i],
    })
end

function sol.main:on_draw(screen)

--clear and overwrite
test = {}

if testing == true then
test[0] = "test_overwrite1"
test[1] = "test_overwrite2"
test[2] = "test_overwrite3"
test[3] = "test_overwrite4"
test[4] = "test_overwrite5"
test[5] = "test_overwrite6"
test[6] = "test_overwrite7"
test[7] = "test_overwrite8"
end

for i = 0,7 do
    show_text[i]:draw(screen,x_test_pos,y_test_pos[i])
  end
end

end

Here you go. You need to have the following in the draw function. You need it to update...

Code ( lua) Select Expand

---IN THE DRAW FUNCTION
for i = 0,7 do
     show_test[rep] = sol.text_surface.create({
      text = test[i],
    })
end

Example:

Code ( lua) Select Expand

local test = {}
local testing

test[0] = "test1"
test[1] = "test2"
test[2] = "test3"
test[3] = "test4"
test[4] = "test5"
test[5] = "test6"
test[6] = "test7"
test[7] = "test8"


function sol.main:on_draw(screen)

---IN THE DRAW FUNCTION
for i = 0,7 do
     show_test[rep] = sol.text_surface.create({
      text = test[i],
    })
end

--clear and overwrite
test = {}

if testing == true then
test[0] = "test_overwrite1"
test[1] = "test_overwrite2"
test[2] = "test_overwrite3"
test[3] = "test_overwrite4"
test[4] = "test_overwrite5"
test[5] = "test_overwrite6"
test[6] = "test_overwrite7"
test[7] = "test_overwrite8"
end

for i = 0,7 do
    show_text[i]:draw(screen,x_test_pos,y_test_pos[i])
  end
end

end

Thank you Zefk! It works now.

I am not sure if I understand the question, but if you want to change the text of a text surface, use the function text_surface:set_text().

Also, instead of manually repeating some code here:

Code (lua) Select Expand


test[0] = "test1"
test[1] = "test2"
test[2] = "test3"
test[3] = "test4"
test[4] = "test5"
test[5] = "test6"
test[6] = "test7"
test[7] = "test8"


you can just concatenate strings:

Code (lua) Select Expand


for i = 1,8 do
  test[i] = "test" .. i
end

(I also changed the loop to go from 1 to 8 (instead of 0 to 7) because this is the usual convention in Lua.)
