The Powder Toy (Subframe Chipmaker Mod)

This is a mod of The Powder Toy for subframe chipmakers. Subframe technology refers to a collection of tricks used to reduce computation cycles in electronic components to a single frame.

For the full experience, add the lines from autorun.example.lua into your autorun.lua.

Features

New features:

• Particle order reloading (shortcut: Shift-F5).
• Subframe animation (shortcut: Shift-Space). Runs the simulation particle-by-particle rather than frame-by-frame.
• Subframe recording (Lua: tpt.record_subframe(true)). Starts a recording of particle-by-particle simulation and automatically stops recording at the end of the frame. You can stop the recording with tpt.record_subframe(false) without stopping particle-by-particle simulation.
• (v1.1) Stack tool (shortcut: Shift-S). Dragging on a stack of particles unstacks them; selecting multiple particles in different positions stacks them in order of their positions.
• (v1.1) Stack mode (shortcut: Shift-D to toggle). Allows you to draw or paste over existing particles, and makes right-click delete one stacked particle at a time. This helps to make things like transparent DTEC.
• (v1.7) Config tool (shortcut: C). Sets particle properties in a few clicks. DRAY: Sets tmp, then tmp2. CRAY: Sets tmp2, then tmp. LDTC: Sets life, then tmp. DTEC/TSNS/LSNS/VSNS: Sets tmp2. FILT: Sets tmp. CONV: Sets tmp (click on another particle with the type you want to set the tmp to).
• (v1.8) Timelapse recording (Lua: tpt.setrecordinterval(<frames>)). Changes the interval that frames are captured when recording. Useful when making timelapses.
• (v1.10) Stack edit (shortcut: X, Shift-X, PageUp, PageDown, Home, End). Config tool, property tool, ctype-draw and subframe debugging (Shift-F) target particles at the selected depth. When stack mode is enabled (Shift-D), particles are created and deleted at the selected depth. Note that using the brush with stack edit messes with particle order, so this is best combined with automatic particle order reloading (tpt.autoreload_enable(1)).

New features enabled by the Lua command tpt.autoreload_enable(1):

• Automatic particle order reloading: If you use the brush or do a copy-paste and then advance the simulation, the frame is completed and particle order is reloaded automatically.
• Backups: Overwriting a local save ".cps" creates a backup of the file you're overwriting at ".cps.backup". Subframe development is dangerous.

Property tool changes:

• P opens the property tool window rather than takes a screenshot. You can still take screenshots with F2.
• (v1.3) "filt:v" in property tool translates into (v<<8) + 125, to aid the configuration of CRAY that creates FILT with a preset tmp.
• (v1.6) 30th-bit handling. Adding "c:" before typing in a number into the property tool when setting ctype sets the 30th bit. For example, "c:50" sets the ctype to (50 | 0x20000000). Works with hex too -- just add "0x", like in "c:0xC0FFEE". (This used to be "c", but was changed due to collisions with element names.)
• (v1.11) Properties in property tool are rearranged so that electronic properties are more conveniently accessible when using arrow keys.
• (v1.12) Property tool stays on the selected property when an invalid value is entered.

HUD changes:

• Stacked particles are shown in the HUD.
• FILT ctypes are displayed in the HUD. In the original game, this was only shown for non-FILT coloured particles like BRAY.
• (v1.6) The property tool no longer sets the 31st and 32nd bits of colored particle ctypes.
• (v1.6) Ctype display modes (shortcut: Ctrl-J to cycle). This changes how the ctype of a colored particle is displayed in the debug HUD. The ctype is displayed in hex by default, but you can switch it back to decimal. For decimal, you can choose to enable 30th-bit handling. This ignores the 30th bit and, if the 29th bit is set, displays the ctype as a negative number.
• (v1.10) The HUD is slightly more compact.
• (v1.11) The subframe debugging position is shown in the HUD.
• (v1.11) CRAY FILT mode is shown in the debug HUD.
• (v1.12) CONV's tmp is presented as an element name, to the left of its ctype.
• (v1.14) WALL type is always shown in the top right HUD.

Other quality-of-life changes:

• Alt-F continues updating particles until it encouters an "interesting" update (create_part, delete_part or part_change_type called), and does not display any log messages until the frame is completed.
• When pasting or placing stamps, the white dotted paste boundary is not shown.
• If you attempt to open a save or close the window with the ESC button (the case for closing with the 'X' button has not been implemented) when there are unsaved changes, a confirmation warning is displayed.
• If you attempt to save when you're in the middle of a frame, a confirmation warning is displayed.
• If you attempt to save when your particles are not in subframe order (and automatic particle order reloading is disabled), a confirmation warning is displayed.
• The position in frame is saved into undo history during subframe debugging, so you can undo into the middle of a frame without destroying everything.
• Applying deco to a stack applies it preferentially to energy particles.
• (v1.1) Creating CRAY with the brush gives it a ctype of SPRK automatically. If you want to create a ctype-less CRAY, use the property tool.
• (v1.10) Tab no longer changes the brush, since it conflicts with Alt-Tab. You can still change the brush with Shift-Tab.
• (v1.12) When pasting or placing stamps, you may use the WASD keys to adjust its position instead of the arrow keys.
• (v1.12) BRAY is visible even when its life is low.
• (v1.13) Paste and stamp previews respect changes to render options, including whether decorations are enabled.
• (v1.14) The ruler tool (enable with tpt.setdebug(0x4), or tpt.setdebug(0xC) to use with subframe debug mode) shows dimensions not just for lines, but also for boxes.

New Lua interfaces:

• tpt.autoreload_enable(enable: int): Enables autoreload if enable = 1, disables autoreload otherwise. Default: enable = 1.
• tpt.record_subframe(start: bool): Start or stop subframe recording.
• tpt.setrecordinterval(num_frames: int): Changes the recording interval to once every num_frames frames.
• sim.reloadParticleOrder(): Reloads particle order.
• (v1.13) tpt.set_bray_life_brightness_threshold(thres: int): Make BRAY visible even when its life is low. thres is added to BRAY's alpha value when it is in the non-solid (i.e. life != 2) state.

Note that the original game already supports the following subframe debugging features (enable with the Lua command tpt.setdebug(0x8)):

• Shift-F updates all particles up to the particle where your mouse is at.
• Alt-F updates a single particle. This behaviour has been modified in this mod to continue updating particles until an "interesting" update occurs.
