You all know 17Smi (see above) that you can install maps HL1, HL2 and mods in a few seconds.
Here now 17's Buddies Integrator Map System (17IMS), still exclusive 17's Buddies, which lets you in two clicks to create a map package, or one of several maps mappack.
This program simply allows you to create an archive file from a half-life map (.bsp) containing all the necessary resources for this map (wads, models, skies, sprites, sons, overviews, etc...) and only those!
Advantage System:
You are a player and when connected to your preferred server, you played on a map that you do not know. The HL engine has therefore you downloaded this map and all its relevant files and installed in your steam directory. Now you want to use this map to your team by creating a zip download , but then, how? What are the files needed and where were they installed?
You are mapper and you have your assets many maps. You just finished your latest work and are ready to upload. But then, when creating the archive, you forget to include a sprite and after publication, is a disaster! Your map bugs and doesn't start.
In both cases, no problem with 17IMS! You select the file from your map bsp and gooooo .... and the zip is created with all its files and you just have to send or upload.
The principle remains the same if you select multiple files: you will have a map-pack ready to install in seconds!
The use of this software is totally free !!
