Interacting With Game

Maybe you need to ask something to user or log something to ui etc. There are functions for them.

cr.log

Used to show log on UI.

Usage:

cr.log(msg, type)

• msg: any string
• type: cr.log_type (see Types)

Examples:

cr.log("Something feels strange", cr.log_type.NORMAL)
cr.log("You are hungry!", cr.log_type.WARN)
cr.log("You cant fight with a god!", cr.log_type.IMPORTANT)

cr.ask & cr.ask_string

Used to get string or key (as integer) from user. cr.ask gets one key including ESC key, cr.ask_string gets a full string.

Example for confirmation dialog:

local key = cr.ask("Confirm [Y/n]: ")
-- some handling here...

Example card uses cr.ask_string function:

cr.create_card({
    count = 2,
    name = "wishing well",
    id = "my_plugin:wishing_well",
    type = cr.card_type.BASIC,
    level_ids = {},
    logmsg = "You found a wishing well",
    ttl = 0,
    event = function()
        -- In this case we get just 2 characters. But you can get any length
        local wish = cr.ask_string("What are you wishing? [hp / zr (zombification reset)]: ")
        if wish == "hp" then
            cr.log("You feel better", cr.log_type.NORMAL)
            return 10

        elseif wish == "zr" then
            cr.log("You're starting to look more like a human.", cr.log_type.NORMAL)
            zombie_buff.level = 0
            return 0

        else
            cr.log("Your wish is ignored", cr.log_type.NORMAL)
            return 0
        end
    end
})
