Knife API v2.2

Knife API v2.2
Version 2.2 released on 21st of July, 2014
Table of Contents
Description topMy first intention for this plugin was for my upcoming RolePlaying mod, however I couldn't find anything like this in the plugins section, so I decided to pre-release it (same as my Database ORM).
Knife API makes adding new knives a breeze due to the knife pickup/switching/dropping mechanism it provides. This way, all knives are added via a standarized way. Version 2.0 has added many new possibilities and functions to the core.
If you have multiple knives, you can cycle between them (or display a menu if you have the cvar enabled) with the R (+reload) key.
WARNING: Plugins written for Knife API <2.0 ARE NOT COMPATIBLE with the latter versions. You will need to port your old plugin. Apologies, hopefully it won't happen again!
Possibilities topThis is a really great tool for plugins which depend on knives (such as knife servers, RolePlaying( ), jailbreak and stuff like that). Creating knives via this will make them seem like seamless addition to the game, especially when combined with custom sprites.
What this plugin can do:- Assign basic values such as models and sounds to a newly created knife
- Custom knife sprites, see examples
- Custom knife range
- Additional delay after the animation start
- Catch events such as attacking/drawing weapon for even more extendability
- Etc.
What this plugin can't do:- While it can do a lot, you still have to put in some work yourself
- There's not much it can't do. It can't make you a sandwich.
Requirements topThe requirements are:- NOTHING RIGHT NOW! YAAY!
Installation, configuration topTo install:
Install like any other plugin. Download the source code, compile it and let other plugins take adventage of it.
To configure:
By default, the CS knife has been removed from game and replaced by Hands (you can see those on Jailbreak). If you want to change this habit, comment #define DEFAULT_HANDS in the source code on line 59. If you do this, you also don't need any of the resources.
To configure the default knife/hands values, edit the __addDefaultKnife() function in the source code on line 203.
Use the following cvars to change the basic plugin functionality:- knifeapi_dropondeath (default:1) - should droppable knives be dropped on the player death? This doesn't remove them from player. You must also use knifeapi_lossondeath!
- knifeapi_lossondeath (default:1) - should player lose all of their knives on death (including droppable knives except the default one)?
- knifeapi_switchmenu (default:1) - when pressing Reload, do you want to display the menu of knives rather than cycling through them?
- knifeapi_roundremoval (default:1) - should knives dropped around be removed on round end?
API (Natives and forwards) topI'll put the .inc file here, the natives and forwards should be explained in it. It won't tell you anything when it comes to writing down the actual plugins, you should look at the examples for that kind of stuff.
PHP Code:
