gPlacer - Mapping utility

A little tool meant to make prop placement easier for mappers by allowing you to place any prop in Gmod and push it to hammer.

I don't do much mapping, but from what little experience I have, I definitely know that I much prefer building and placing props in Gmod over trying to meticulously place them in Hammer.


Usage
To enter gPlacer mode, enter in to console: GPLACER_TOGGLE

While in Gplacer mode, all props you spawn will be marked as being Gplaced.

Hammer and Garrysmod must both be running at the same time and Steam must be running as administrator. Furthermore, this will only work if you are hosting the game off of your computer (singleplayer/listen server).

The map file's name name must be the exact same in Hammer as it is in Gmod!
To send all placed props to hammer, enter into console: GPLACER_UPDATE

You can move the props, remove them, or add new ones and updating with GPLACER_UPDATE will reflect these changes in Hammer without creating multiple versions of each prop.

You can change the entity class with the command: 'GPLACER_CLASS class_name'
By default this is prop_static.

Features
- Props placed in gmod will replicate to hammer
- Changes to props, such as modifying their position, removing them, or re-coloring them will apply automatically, no need to delete old placed props manually.
- Ropes can be gplaced, even when they've been placed on entities.
- Ragdolls spawned in Gplace mode will be treated as effects.

Note: This addon updates your gplaced entities by finding entities in hammer that match the exact position, if you want to make a change to an entity after placing it, but don't want it to be re-initialized after being edited, very slightly change it's position.

protip: add "-windowed -noborder" to your command line on gmod in order to play the game in borderless windowed mode for easier alt-tabbing.

**NOTICE**
Some props may dissapear when you compile the map if they are static props, this is because of an arbitrary limitation in the Source engine, however, there is a custom Compiler that will allow you to get around this, and many other weird limitations.
