Hey, how to render Text on Screen ?

i found this function:

/c
local entity = game.player.selected
	rendering.draw_text 
		{
			text = "TEST", 
			scale = 1.4,
			color = {255,0,0},
			surface = entity.surface, 
			target = entity
		}

i wanted to move Text UP but and right but im not sure how to use:

Code: Select all

target_offset = right = {1.0, 0.0}

+ Is it possible to use TEXT Formating like for Chat and BP Library?
im asking about Font and Color TAGs

[font=default-large-bold][color=255,190,255]🅃🄾🄱🄸[/color][/font]

LuaRendering is used to render things into the game world. If you are wanting to place text onto the players screen then you will want to use a GUI.

There is a gui position referenced by LuaPlayer.gui.screen which you can then add labels onto.
Once you add a label onto a player's screen you can change its position with LuaGuiElement.location to be where you want it.
With GUI labels you can set their style to allow rich text elements with LuaGuiElement.style.rich_text_setting.

However, if you are wanting it to be connected to an entity then you are right to use LuaRendering.
To use target_offset you need to include it in the table you are passing to draw_text.
Like all positions in the game, a vector of {1,1} will be down and right so you will want {1,-1} or some scalar of it.
The vector will also be in number of tiles, you can see the tile grid with the debug option (f4) "show-tile-grid".
Color should be done with the color property, however there is no way to make rich text work with LuaRendering see this post.

I just want to create some Text over some objects like for example:

: 427520_20200610004815_1.png (1.44 MiB) Viewed 1534 times

Code: Select all

/c
local entity = game.player.selected
	rendering.draw_text 
		{
			text = "Sell Circuits", 
			scale = 1.4,
			color = {255,120,0},
			surface = entity.surface, 
			target = entity,
			target_offset = {-1.4, -3.0}
		}

This code works fine... but egh :c...
its hard to setup Text in correct place... i was trying 10 times before it was in center and over market

Bfff ok... Topic can be closed or something... idk...
im just gonna fuck with draw_text function...

I already tested and i can use this function multiple times on single entity so if i want multi colored text...
it will take while but i can do it with this function xD

What might be useful is if you use "alignment" with draw_text.
The default is to align the left corner, if you set the value to "center" then you dont need to worry about the x offset.

Calling the function multiple times wont remove the old ones that were added.
So you will want to use LuaRending.destroy to stop it from possibly lagging the game.
( I once made this mistake with map tags, after a few hours of game play there were hundreds of tags on the map all overlapping )
