Modify unit's displayed stats

[The_Gnat]

This is a rather odd question but I assume it is possible.

It is rather easy to modify a units stats with an [object] and [effect]. But what if you don't want to change the stats, only change the displayed stats.The situation is that I want a unit to have 6MP on water and 4MP on land. But that is not possible because if I set it to 6MP (movement cost water =1, movement cost land = 1.5) That is clearly going to break.

So what I thought is instead I can set 12MP and movement cost water = 2, movement cost land = 3. Then by setting vision = 6 it acts exactly how I want to. However, then the player sees the number 12MP on the unit bar. Which is weird

So then I thought all I need is an event that makes the units MP stat display as only 6 instead of 12mp.

This is the stat I want to change:

The reason I ask is because I assume it is possible to modify the display because I can add an icon to the menu bar like this:

Code: Select all

[event]
    name=turn refresh
    #first_time_only=no

    [lua]
        code=<<
            local _ = wesnoth.textdomain "wesnoth-ROTL"
            local old_unit_status = wesnoth.theme_items.unit_status
            function wesnoth.theme_items.unit_status()
                local u = wesnoth.get_displayed_unit()
                if not u then return {} end
                local s = old_unit_status()
                if u.status.ROTLensnared then
                    table.insert(s, { "element", {
                        image = "misc/web-status.png",
                        tooltip = _"ensnared: This unit is ensnared. Ensnared units' defenses are reduced to 10% making them vanurable to enemy attacks. Units remain ensnared for 1 round."
                    } })
                end
                return s
            end
        >>
    [/lua]
[/event]

Here with this code I am able to insert an element into the display table so I assume with some other code (which I currently have no idea about ) I might be able to modify the displayed MP.

It is not really documented, but wesnoth.theme_items should have all the elements you need.

Okay great I will see if I can find out about that!

I think you want wesnoth.theme_items.unit_moves and .selected_unit_moves too. See https://github.com/wesnoth/wesnoth/blob ... #L684-L693.
