More ModScript examples
« on: January 07, 2020, 07:52:42 pm »
So, I've been working on some ModScripts for OXCE+ and wanted to share what I have so far.

I am actually aiming for some documentation of the various scripting possibilities but did not yet find the time to write something meaningful. So examples will have to do for know.

I will start of with two of my debug scripts which I used for some damage scaling and understanding how XCOM applies damage. (See attached file debug.rul)

I am using two hooks which are part of the hit and damage calculations: hitUnit and damageUnit.

Both are called in quick succession after each other, every time a unit will potentially receive damage.

The first hook (hitUnit) receives power, part and side and is expected to also return these values. So we have the opportunity to change the power of an attack, the body part which was hit or the side of the armor where the hit connected.

The second hook (damageUnit) has variables for all the damage that is applied after a succesful hit (like to_health, to_armor, to_stun, etc.). Here you can change the amount of damage that is applied to the respective type.

One potential use of this would be a weapon which enables for body part targeting. I have included such an example as bodypart_targeting.rul.

We define three new Tags: AUTO_IS_KNEESHOT, AUTO_IS_ARMSHOT & AUTO_IS_HEADSHOT. When applied to a gun, the scripts will check for that tag on the weapon and apply fatal wounds to the bodypart which has been targeted.

(My meal is getting cold, so I will add more information later..;)

Here I will post some scripts I use to fine-tune the game experience to my liking
1. Alien Exposer
This one negates the vision advantage of the aliens and makes XCOM units see as good as them.
2. Accuracy Nerfer (Adjuster ;)
Allows global changes to the accuracy of all alien units. I use this if I think the aliens are aiming a bit too good  ;D Of course it can be used to make the Game even harder by just globally increasing the accuracy of your foes.
3. Power Nerfer
Same as the above. Allows global attack power adjustment of the enemies. Could also be used to make them hit harder..
4. Critical hits. Code for simple critical hits. Might still be a bit finicky. I use this because I play with with a very low damageRange.

Code: [Select]

I will put this here, since I do not know where to put this otherwise ;)

Code: [Select]
# weapon proficicency system - by memmaker
#
# how to use: flag weapons with WEAPON_TYPE tags
# eg. You decide all shotguns are weapon type 3
# Then you would have something like this:
# items:
#   - type: STR_SHOTGUN
#     tags:
#       WEAPON_TYPE: 4 # shotguns
#   - type: STR_ALLOY_SHOTGUN
#     tags:
#       WEAPON_TYPE: 4 # shotguns
#
# You can decide which WEAPON_TYPE entry to use by using this table:
#
# Type 1 -> WEAPON_TYPE: 1
# Type 2 -> WEAPON_TYPE: 2
# Type 3 -> WEAPON_TYPE: 4
# Type 4 -> WEAPON_TYPE: 8
# Type 5 -> WEAPON_TYPE: 16
# Type 6 -> WEAPON_TYPE: 32
# Type 7 -> WEAPON_TYPE: 64
# Type 8 -> WEAPON_TYPE: 128
#
# NOTE1: The current script only allows for a maximum of 8 different weapon types. Could be expanded.
#
# All hits with weapons which are tagged with WEAPON_TYPE will be tracked.
# After the hit_limit is reached (search for "set hit_limit" if you want change it),
# the soldier is awarded the proficiency with this weapon type.
#
# A soldier's accuracy with a proficient weapon is increased (defined at "set accuracy_bonus").
# IMPORTANT: If a soldier has weapons in both hands the bonus of the right hand weapon is applied.
#            The technical reason for this is, that we do not know for which item an accuracy bonus is being calculated.
#            Also, having a proficient weapon equipped also boosts PSI accuracy, since the bonus is not bound
#            to a specific action.

I will put this here, since I do not know where to put this otherwise ;)


This is blowing my mind, thanks for posting this.

Here I will post some scripts I use to fine-tune the game experience to my liking
1. Alien Exposer
This one negates the vision advantage of the aliens and makes XCOM units see as good as them.
2. Accuracy Nerfer (Adjuster ;)
Allows global changes to the accuracy of all alien units. I use this if I think the aliens are aiming a bit too good  ;D Of course it can be used to make the Game even harder by just globally increasing the accuracy of your foes.
3. Power Nerfer
Same as the above. Allows global attack power adjustment of the enemies. Could also be used to make them hit harder..
4. Critical hits. Code for simple critical hits. Might still be a bit finicky. I use this because I play with with a very low damageRange.

Code: [Select]
extended:
  tags:
    BattleUnit:
      CRITICAL_STATE: int
    RuleItem:
      CRIT_CHANCE: int
      CRIT_DAMAGE: int
  scripts:
    visibilityUnit:
      - offset: -1 # alien exposer
        code: |
          var ptr RuleArmor armor_rule;
          var ptr RuleSoldier soldier_rule;
         
          observer_unit.getRuleSoldier soldier_rule; 

          if neq soldier_rule null;  # we have an xcom unit as observer
            if le distance distance_max;
              set current_visibility 100; # expose enemy unit if in max viewing dist (like the aliens..)
            end;
          end;
          return current_visibility visibility_mode;
    createUnit:
      - offset: -1 # accuracy nerfer
        code: |
          var ptr RuleSoldier soldier_rule;
          var int id;
          var int firing;
          var int adjustment;
         
          set adjustment 90; # 90% accuracy

          unit.getId id;
          unit.getRuleSoldier soldier_rule; 

          if eq soldier_rule null;  # we have an alien unit
            debug_log "Adjusting accuracy of unit" id;
            unit.Stats.getFiring firing;
            debug_log " - from" firing;
            muldiv firing adjustment 100;
            unit.Stats.setFiring firing;
            debug_log " - to" firing;
          end;
          return;
    hitUnit:
      - offset: -1 # power nerfer
        code: |
          var ptr RuleSoldier soldier_rule;
          var int id;
          var int firing;
          var int adjustment;
         
          set adjustment 70; # 70% power

          unit.getId id;
          unit.getRuleSoldier soldier_rule; 

          if neq soldier_rule null;  # we have an xcom unit
            debug_log "Adjusting power of hit against xcom unit" id;
            debug_log " - from" power;
            muldiv power adjustment 100;
            debug_log " - to" power;
          end;
          return power part side;
    damageUnit:
      - offset: -1 # critical hits (balancing for lower damageRange)
        code: |
          var ptr RuleItem item_rule;
          var int weapon_chance;
          var int unit_chance;
          var int chance;
          var int crit_factor;  # 100 = 100% additional damage of original power
          var int crit_damage;

          weapon_item.getRuleItem item_rule;

          unit.getTag unit_chance Tag.CRITICAL_STATE;
          item_rule.getTag weapon_chance Tag.CRIT_CHANCE;
          item_rule.getTag crit_factor Tag.CRIT_DAMAGE;

          add unit_chance weapon_chance;

          if eq unit_chance 0;
            set unit_chance 5;  # base chance of 5% for everybody
          end;

          if eq crit_factor 0;
            set crit_factor 20; # 20% additional damage as baseline for everybody on crit
          end;

          battle_game.randomChance unit_chance; # will set unit_chance to 1 on success
          if gt unit_chance 0;
            set crit_damage orig_power;
            muldiv crit_damage crit_factor 100;
            add to_health crit_damage;
            debug_log "CRITICAL HIT:" crit_damage;
          end;
          return;

 Curiously, is there a way to make critical hits negate a portion of armor instead?

It should be possible, it would need some code to "revert" part done in engine, but most needed variables are avaialbe in scripts.

[ps]
One big drawback I find, `ArmorEffectiveness` is not exposed to scripts, this mean you need guess what values was.
Probably easiest way would be ignore complete current behavior of engine and write your own damage mechanism :D
I will look in this week if I can add details of damage type to scripts.

While it's not exposed, can you still set the armor or armor effectiveness to 0?

Thanks for peeking into it. I really need to look into the code deeper and see about if I can create more hooks. An inventory iterator would be nice like getInventoryArray()

Yes, this is one option, and then in script (`hitUnit`) manually subtract armor value using your own logic. Probaby better is alter effectiveness  as is not avaiable to scripts right now (unit armor is).

Loops are on my TODO, this is bit tricky because I need made some refactors to make them easy to use and safe (I would prefer that scripts can't hang whole game).

I've always wondered how noticeably y-scripts can affect game performance? After all, some are called quite often (each frame). Are there any recommendations about this, restrictions? Say, if my y-script will consist of 5 thousand lines of calculation code? Or 10? Could there be a difference between hooks?

y-scripts was designed to DRAW graphic (or at least alter pixels it in arbitrarily way).
Last time I check budget was around 100M script operations per second or something this magnitude.
More important question is what you script do exactly, because some functions could do lot of things (like getting rules by name or finding item in inventory).

For now, I was only using tag loads, things like getting an attacker unit or damaging item. Now sure how expensive those operations are.

Most of them are relative cheap. And for overall performance, check how often given hook is call, if you do not fill up debug output limit then you should not worry about performance even if you have complex script.

Set Armor effectiveness to 0 or .25 or whatever fits. Got ya.

4. Critical hits. Code for simple critical hits. Might still be a bit finicky. I use this because I play with with a very low damageRange.

I've been playing around with the critical hit code, combining it to the "turn red for one frame" code and a message to show critical hits.
Code: [Select]
extraStrings:
  - type: en-US
    strings:
      STR_CRITICAL_HIT_MESSAGE: "Critical hit!"
extended:
  tags:
    BattleUnit:
      CRITICAL_STATE: int
      LAST_HIT_FRAME: int
    RuleItem:
      CRIT_CHANCE: int
      CRIT_DAMAGE: int
  scripts:
    # Future Script for luck
    #
    # Script for Criticals
    damageUnit:
      - offset: -1 # critical hits (balancing for lower damageRange)
        code: |
          var ptr RuleItem item_rule;
          var int weapon_chance;
          var int unit_chance;
          var int chance;
          var int crit_factor;  # 100 = 100% additional damage of original power
          var int crit_damage;
          var int temp;

          weapon_item.getRuleItem item_rule;

          unit.getTag unit_chance Tag.CRITICAL_STATE;
          item_rule.getTag weapon_chance Tag.CRIT_CHANCE;
          item_rule.getTag crit_factor Tag.CRIT_DAMAGE;

          add unit_chance weapon_chance;

          if eq unit_chance 0;
            set unit_chance 5;  # base chance of 5% for everybody
          end;

          if eq crit_factor 0;
            set crit_factor 100; # 100% additional damage as baseline for everybody on crit
          end;

          battle_game.randomChance unit_chance; # will set unit_chance to 1 on success
          if gt unit_chance 0;
            set crit_damage orig_power;
            muldiv crit_damage crit_factor 100;
            add to_health crit_damage;
            # Flash RED when crit hit
            # NEED TO BUILD IN A CHECK TO SEE IF ITS WEAPON DAMAGE FFS
            battle_game.flashMessage "STR_CRITICAL_HIT_MESSAGE";
            battle_game.getAnimFrame temp;
            unit.setTag Tag.LAST_HIT_FRAME temp;
            debug_log "CRITICAL HIT:" crit_damage;
          end;
          return;

    recolorUnitSprite:
      - offset: 10
        code: |
          var int temp;
         
          unit.getTag temp Tag.LAST_HIT_FRAME;
          if neq temp 0;
            sub temp anim_frame;
            if gt temp -3; #only 3 frames after hit have changed color
              set_color new_pixel 2; #red color
            end;
          end;
         
          return new_pixel;

I need to figure out
1) How to connect it to shoot script, since I'd love to have it as 5% for snap shots, 1% for auto shots and 10% for aimed shots.
   a) Also I need it to stop declaring critical hits for smoke
2) How to change the code so that it leaves off a damage roll and just gives the base damage number (100%) and then reduces armor effectiveness to 0.25

But I haven't been playing with it all that much yet. Too busy streaming.

Thanks for posting this up.
