====== Conditions (YAML) ======

Conditions are used in ''if:'' fields on events, choices, actions, conditional text blocks, ticks, ''visible-if:'' and ''disabled-if:''.

===== Base Syntax =====

^ Condition ^ Meaning ^
| ''~'' | Always true fallback. |
| ''v_hp_v = 0'' | Variable equals 0. |
| ''v_hp_v != 0'' | Variable is different from 0. |
| ''v_hp_v > 5'' | Greater than 5. |
| ''v_hp_v >= 5'' | Greater than or equal to 5. |
| ''v_hp_v < 10'' | Lower than 10. |
| ''v_hp_v <= 10'' | Lower than or equal to 10. |
| ''v_hp_v in 3-7'' | Inside range 3 to 7. |
| ''v_hp_v out 3-7'' | Outside range 3 to 7. |

===== Compare Two Variables =====

<code yaml>
if: "v_hp_v > v_enemy_hp_v"
if: "v_score_v = v_record_v"
</code>

===== Multiple Conditions =====

Separate conditions with a space. They are combined with AND.

<code yaml>
if: "v_hp_v >= 5 v_gold_v >= 10 key"
# HP >= 5 AND gold >= 10 AND object key owned
</code>

===== Inventory Objects =====

Objects are tested with their raw name:

<code yaml>
if: "key"      # player owns object key
if: "-key"     # player does not own object key
</code>

Do not use ''o_key_o'': that is not the YAML condition syntax.

===== Choices =====

<code yaml>
choices:
  - command: open
    button: "Open the chest"
    to: chest_open
    if: "key"
    text_ko: "You need a key."
  - command: force
    button: "Force the lock"
    to: chest_open
    if: "v_strength_v >= 8"
    disabled-if: "v_strength_v < 8"
</code>

  * ''if:'' blocks access if false.
  * ''text_ko:'' is displayed when ''if:'' fails.
  * ''visible-if:'' hides the button if false.
  * ''disabled-if:'' keeps the button visible but disabled if true.

===== Conditional Text =====

<code yaml>
text:
  - if: "v_hp_v <= 0"
    text: "You are down."
  - if: "v_hp_v <= 5"
    text: "You can barely stand."
  - text: "You feel fine."
</code>

The first true block is displayed.
