Spells Tutorial

Find the spells listing on your mod page and click New Spell. Fields explained:

Field	Explanation
Name	Name your spell. Do not make it too long so it will fit in the spell icon.
Mana	Mana cost. This can be set to negative as a lazy way to make a spell restore mana.
CD	Spell cooldown. Global cooldown set in class will be used if this is lower than that.
Range	Spell range. Do not use more than 10. You can click melee and spell buttons to use the default values.
Cast time	Cast time for spell in whole seconds. Use 0 for instant cast.
Texture	Texture of your spell icon. You can get the got_spells.psd template here.
Charges	Spells with cooldowns can have multiple charges. When the cooldown finishes it gains a charge. Many tank and instant cast spells use this.
Stance Override	Allows you to override the default stance for your class.
Opponents	Allow spell to target enemies.
Caster	Allow spell to target owner.
Friends	Allow spell to target friendly targets.
No Facing Req	By default you must face the target of your spell. With this checked you do not have to. Usually used on healing spells.
AoE	Casts as an area effect.
No Global CD	Does not trigger the global cooldown. This is often used on tank mitigation spells and ultimates.
No crits	Spell cannot crit. Often used on DoT and HoTs and buffs.
Mobile	Allows spells with a cast time to be used while moving.
Draw Weapon	Causes the player to draw their weapon when using this ability.
Description	Describe what your spell does.
Visual	Sets visual effects that are rezzed, animations, and weapon trails. See below.

Passives	Passives that are granted to the player when they have the class and spec that has this spell active.

Visuals

The Visual field should consist of an array structured as such:

[
  [ // Rezzables
    [
      (str)object_to_rez,
      (vec)pos_offset_from_target_center,
      (rot)rot_offset_from_target_facing,
      (int)flags
    ],
    ...
  ],
  (str/array)finish_cast_anim,
  (str/arr)finish_sounds,
  [ // Class vis / weapon trails
    -2, // This is needed for legacy reasons
    [ // These are passed to classAtt. See below.
      (int)cast_id,
      (int)finish_id
    ],
    [ // These specify weapon trails. See below for more info.
      [
        (int)generator_prim,      // default 0
        (int)age_100ths,          // Default 50
        (vec)color,               // Default <1,.5,.5>
        (int)scale_100ths,        // Default 30
        (int)alpha_10ths,         // Default 5
        (int)glow_10ths,          // Default 3
        (int)duration_100ths,     // Default 70
        (int)predelay_100ths,     // Default 30
      ],
      ...
    ]
  ],
  (str/arr)cast_anims,
  (str/arr)cast_sound
]

Rezzables

This is an array of sub arrays containing items that should be rezzed when the spell cast is finished. Items are rezzed from the yellow effect repo below the HUD.

Position and rotation are relative to the avatar rotation and height. So <1,0,0.5> will always rez 1m in front of the avatar and 50% between pelvis and top of head.

Flags are defined in got SpellFX.lsl

Flag	Hex	Description
SpellFXFlag$SPI_FULL_ROT	0x1	By default the rotation calculations are only based on target Z rotation. If this is set, the projectile will also take avatar up/down rotation into consideration when rezzing.
SpellFXFlag$SPI_TARG_IN_REZ	0x2	Sets the on_rez integer of the rezzed prim to an integer version of the first 8 characters of the target UUID. This is used in many "bolt" type projectiles to fast scan for their target.
SpellFXFlag$SPI_SPAWN_FROM_CASTER	0x4	Only works on targeted spells. Spawn the projectile on the caster instead of the target. Useful for bolt type visuals.
SpellFXFlag$SPI_IGNORE_HEIGHT	0x8	By default the Z position is multiplied by avatar height/2. This will ignore that. So if you set a Z position of 0.5 then it always spawns 0.5m above target pelvis.
