• Spawn items:
  • Either under the object when you lift it, or falls out of it when you break it; configurable per-combo
  • Either from a dropset, or pre-set items
  • Either every time, or as a "Special Item"; i.e. Heart Piece under a rock. This mode will set Screen->State[ST_SPECIALITEM] when you pick it up, so no other special item can be on the same screen.
• Hurt enemies:
  • Deal damage with the thrown object; amount configurable per-combo
• Carry across screen borders (toggle-able per-bracelet item)
• Carry in water (toggle-able per-bracelet item)
• Drop what you are holding when hit (toggle-able per-bracelet item)
• GFX/SFX:
  • Use a "Weapons/Misc" sprite upon the object breaking (configurable per-combo)
  • Play an SFX when it breaks (configurable per-combo)
  • Undercombo- either use the screen's undercombo, or use the next combo in the list (toggle-able per combo)
• Lift from layers (which is TEMPORARY layer alteration; as one would want for this!)

Minimum ZC version: 2.55 Alpha 40

Credit to ywkls for inspiration/idea (and 'ComboInFront(int dir)'), and to Moosh for 'scrollingDraws.zh', which I modified for this.
Note: The modified scrollingDraws.zh is no longer present as of V2.1.0. Scrolling draws still work, using 2.55's 'Game->Scrolling[]' system.
Changelog:
02-Nov-19 - V1.0.0 uploaded
03-Nov-19 - V1.0.1 - Lift/Throw SFX (d6/d7) added
22-Nov-19 - V2.0.0 - Overhaul. Change setup. Add lifting from layers.
24-May-20 - V2.1.0 - Remove the modified 'scrollingDraws.zh' code, use 'Game->Scrolling[]' from 2.55 instead.
12-Feb-22 - V2.1.1 - Minor update: Clarify instructions, add Player Tile Modifier option

DISCLAIMER: If you encounter any issues with using this script, PLEASE DO LET ME KNOW SO I CAN FIX IT.

Only std.zh is required.

HELD_DRAW_LAYER - the layer to draw the held object to (default 3)
WEAPON_DRAW_LAYER - the layer to draw the thrown weapon to (default 3)

ITEM:

• Set the flag "Constant Script" (Flag 15)
• Assign the script to the "Action" slot
• Set up parameters:
• d0 - the Step of the thrown lweapon (movement speed)
• d1 - the initial Jump of the thrown lweapon (vertical movement)
• d2 - Lift Delay (the number of frames it takes to lift an object)
• d3 - Custom animation:
• To use no custom animation, set this to 0
• To set up a custom animation:
• Create 16 combos in a row.
• First 4: Up,Down,Left,Right - standing still
• Second 4: Up,Down,Left,Right - walking
• Third 4: Up,Down,Left,Right - swimming
• Fourth 4: Up,Down,Left,Right - Lifting
• Set d3 to the upper-left combo (up-facing, standing still), and this will be used.
• UseSound: The value set as the sound will be used for the 'Lift' SFX. The next sound after this (n+1) will be used for the 'Throw' SFX.
• Flags
• Flag 0: Can carry while swimming
• Flag 1: Will drop held object if hit
• Flag 2: Can carry across screens

No setup is required for the lweapon script, though make sure it is assigned to a slot!
For EACH COMBO:

• Set up type/flag
  • EITHER set the type to 'Bush->Next', OR set the inherent flag to 'Pot, Liftable (Scripted)', 'Pot, Slash or Lift (Scripted)', or 'Rock, Lift Normal (Scripted) to have the combo be liftable.
  • If you instead set the inherent flag to 'Rock, Lift Heavy (Scripted)', it will only be liftable if the bracelet item has a 'Power' higher than '1'.
• Set up Attributes
  • Attributes[0] - Weapons/Misc sprite to use on breaking the object
  • Attributes[1] - Damage done by the thrown object
  • Attributes[2] - If positive, the item ID to drop when broken. If negative, the item dropset to drop an item from when broken.
  • Attributes[3] - SFX to play when broken
• Set up Misc Flags
  • Flags[5] - If this is checked, the next combo in the list will be used instead of the undercombo. (Bush->Next combotypes always do this)
  • Flags[6] - If this is checked, the item will only be dropped once (as the screen's Special Item).
  • Flags[7] - If this is checked, the item will drop when the object breaks, instead of when you lift it
