Prop Line Tool
Draw lines of props and trees like how you draw roads!

This mod will save you time by placing items one by one for you!

The prop offset has been fixed! Big thanks to SamsamTS for the Prop Precision mod!

- Still need to delete items one by one
- Items placed with this mod do count towards their respective item limits
- See "Quirks" section

- Click to place curve control/draw/anchor points.
- Right-Click to cancel the last point.
- Ctrl-Z at any time to undo the last segment, up to the last 64 segments.
- Alt-Click (purple) any time items are showing to copy-place them where they are without having to redraw the curve.
- Ctrl-Click (green) when placing the last control point (items are showing) to Lock the curve in place.
Once in Lock Mode:
- Click any of the control-points to move them.
- Click on the position of the second item to change item spacing.
- Click on the angle locus (large circle with satellite circle) surrounding the second item to change prop angle.
- Click on the curve itself to reposition it.
- Right click when changing something in Lock Mode to revert it to its last state/place before you "picked it up."
To Place Items and Exit Lock Mode:
- Ctrl-Click or Ctrl-Enter to place items and continue/"unLock".

Options Bar
- This mod places an options bar in the same place and style as where the road tool does in order to switch to Straight/Curved/Freeform draw modes.
- Options Bar will appear whenever a tree or prop is selected.
Buttons on the Options Bar:
- Toggle Fence Mode
- Single: default prop and tree singular placement (hides fence mode and control panel buttons)
- Straight
- Curved
- Freeform
- Toggle Control Panel: Show/Hide PLT's handy control panel.

Control Panel
- Click the button in the Options Bar to show/hide.
Control Panel Features:
Parameters Tab:
- Decouple Button (will show when drawing continuous curves. click to reset items to start of curve.)
- Spacing adjustment buttons and textbox
- Angle adjustment buttons and textbox
- Angle Mode dropdown
- Dynamic: angle items relative to the curve.
- Single: angle items with absolute angle on the game map.
Options Tab: (hover over these checkboxes in-game to see more info)
- Show Undo Previews
- Enable Error Checking
- Show Error Guides
- PLT Anarchy: ignore placement errors and place everything
- Place Blocked Props: like Anarchy but only for items that would be "hidden" by roads and/or buildings that already exist. (Use Prop Anarchy if you want the items to not be "hidden"/blocked).
- Render Items at Vanilla Positional Resolution (see "Quirks" section below)
- Use Mesh for Center Correction: If you have props that are not properly centered within their bounds, attempt to center them based on their mesh's pivot point (if available). On by default.

- You may notice that placed items are not perfectly positioned as they appear when drawing the curve. (Especially when using small items or small spacing). This is a limitation due to the method the game uses to compress position-data for each prop/tree.
*NEW*: Use the Prop Precision mod to fix this issue.

If you'd like to preview exactly where items will be placed at vanilla resolution, I've provided a check-box in the Options tab of the control panel called "Render Items at Vanilla Positional Resolution".

- There may be a bit of lag when switching prefabs. I think this is due to the game reloading custom brushes in the brush panel each time a prefab is selected. (Especially in map editor or with a tree brush mod). A workaround is to temporarily move any custom brushes out of the CS brushes folder.

Usage Tips
- Use larger fence pieces where you can to save on prop count. It really makes a difference in the end!
- Place props/trees on roads and through buildings: Enable "Place Blocked Items" in the Options tab of the PLT Control Panel AND enable Prop Anarchy.

@RaeNut thanks for pointing that out. @Alterran, it would be nice to get that pointed out in the controls list.
RaeNut Jul 11 @ 10:24am 
yea i found out the problem with prop anarchy i had to go into the plt's options and set it's version of prop anarchy on.

This mod is working fine with Mass Transit.

I've created a PLT FAQ and PLT Troubleshooting Guide to better address common issues.

If the mod's buttons are not appearing, please read the Troubleshooting Guide .

If you are trying to place items on roads, please read the FAQ .

@Overlord, It's a good idea and it's definitely on my list (:

@fackförbund, It is not unrealistic to ask. Though, as cool as that would be, I would not expect a feature like that anytime soon.

@RockRaid #PrayForNarnia, I will definitely look into adding hotkeys to change spacing. For now, you can use the buttons in the control panel as well as the change-spacing-node in "edit mode" or lock mode.

@soundersbloke, It's probably not this mod that disabled your better bulldozer mod. Though, I am curious. Please send a screenshot of the error messages along with your output log . Whenever you see error messages it is a good idea to save your output log from that session. It contains valuable info to help diagnose the issue.

First of all, great mod! Massively increases productivety. Would it be possible to add hotkeys to increase/decrease the distance between objects?
soundersbloke Jun 25 @ 1:37pm 
When I loaded this mod, it doesn't work and automatically disabled my "better bulldozer" mod. Also, right after enabling this mod, I got several error windows pop open.
RaeNut Jun 23 @ 4:40pm 
It's not working with prop anarchy for me, anyone else? I tried using the line tool next to a road and the game won't place them
fackförbund Jun 23 @ 6:13am 
Is it to unrealistic to ask for a function that automatically fills in a selected area with trees or bushes in a symmetrical matter?
kefflu Jun 21 @ 8:52am 
This Mod dosen't work. There are no icons for it on my UI even though I have it installed and "ON". Too bad, cause I cant make realistic road connections or on and off ramps for freeways. I see no point in playing CS without being able to do this.
