Adding a plugin

Adding new plugin requires including DLRCore.sp file, and implementing following methods:

/**
 * Called when player changed class
 *
 * @param client         The client index of the player playing tetris.
 * @param className      Classname that user just selected
 * @param previousClass  Previous class of user
 * @noreturn
 */
forward OnPlayerClassChange(client, className, previousClass);  

/**
 * Called when player uses special skill. 
 * Plugin should react to this to initiate the skill, then call either or OnSpecialSkillFail / OnSpecialSkillSuccess
 * @param client         The client index of the player playing tetris.
 * @param skillName      Skill that user just used
 * @noreturn
 */
forward OnSpecialSkillUsed(client, skillName);  


/**
 * Called when player has successfully used special skill. 
 * This is required for plugin to implement
 *
 * @param client         The client index of the player playing tetris.
 * @param className      Skill that user just used
 * @noreturn
 */
native void OnSpecialSkillSuccess(int client, char[] skillName);  

/**
 * Called when player has failed using special skill. This prevents from affecting the inventory.
 *
 * @param client         The client index of the player playing tetris.
 * @param className      Skill that user just used
 * @param reason         Reason for failure
 * @noreturn
 */
native void OnSpecialSkillFail(int client, char[] skillName, char[] reason);  

/**
 * Register skill from plugin
 *
 * @param client         The client index of the player playing tetris.
 * @param className      Skill that user just used
 * @param reason         Reason for failure
 * @noreturn
 */
native int RegisterDLRSkill(char[] skillName);  

Native helper methods that are available:

/**
 * Called when player uses special skill. 
 * Plugin should react to this to initiate the skill, then call either or OnSpecialSkillFail / OnSpecialSkillSuccess
 * @param skillName         The client index of the player playing tetris.
 * @param skillId     Assign ID to this var
 * @noreturn
 */
forward FindSkillIdByName(skillName, skillId);  

/**
 * Get player classname
 *
 * @param client  Client index.
 * @return        Classname
 */
native int:GetPlayerClassName(client);

Add DLRCore.sp in your include folder and make sure you have dlr_talents.smx available. Include this in the plugin file header that you want to implement

/****************************************************/
#tryinclude <DLRCore>
#if !defined _DLRCore_included
	// Optional native from DLR Talents
	native void OnSpecialSkillSuccess(int client, char[] skillName);
	native void OnSpecialSkillFail(int client, char[] skillName, char[] reason);
	native void GetPlayerSkillName(int client, char[] skillName, int size);
	native int  RegisterDLRSkill(char[] skillName, 0);  
#endif
static bool DLR_Available = false;
#define PLUGIN_SKILL_NAME "Plugin Name"
/****************************************************/

Include these functions;

public void DLR_OnPluginState(int pluginstate)
{
	DLR_Available = IntToBool(pluginstate);
	g_iClassID = DLR_Available ? RegisterDLRSkill(PLUGIN_SKILL_NAME, 0) : -1;
    ....
}

public void OnPluginStart()
{
....
	if (DLR_Available) {
		g_iClassID = RegisterDLRSkill(PLUGIN_SKILL_NAME);
}

public void OnSpecialSkillUsed(int iClient, int skill)
{
	if (skill == FindSkillIdByName(PLUGIN_SKILL_NAME) {

		CMD_MainMenu(iClient, 0);
	}
}
public void OnSpecialSkillSuccess(int iClient, int skill)
{
	if (skill == FindSkillIdByName(PLUGIN_SKILL_NAME) {

		CMD_MainMenu(iClient, 0);
	}
}
public void OnSpecialSkillFail(int iClient, int skill, char[] reason)
{
	if (skill == FindSkillIdByName(PLUGIN_SKILL_NAME) {
		CMD_MainMenu(iClient, 0);
	}
}

l4d2_dlr's Issues

Problems Arise

In Campaign game, Engineer class can not press Shift key in the next chapter. Thank you for updating this plugin!

Engineer Exploits and bugs.

using a separate plugin for the turrets is a bad idea, ALL of the servers using this method for the turrets have a major exploit.

when an engineer places a turret they call a command to tell the turrets plugin to spawn the turret, however this command can easily be found and used by anyone. SI players can spawn delete turrets, so can nonengineer players.

there is/was? also a bug, if a turret fails to spawn it will still count towards built items meaning you can potentially use all your builds without actually building anything. this issue was fixed in my version by combining the 2 plugins into 1 and adding checks to make sure spawns were successful.

issues with commando

In getdamage(client) function there is a typo on line 1940,

if (StrContains(ClientData[client].EquippedGun, "commando", false)!=-1)

should be

if (StrContains(ClientData[client].EquippedGun, "sniper", false)!=-1)

as it is commando wont get any damage bonus while using sniper.

also around line 1037 commando bonus damage is being assigned twice.

Damage for commando is assigned per hit ray so a rifle will do say 1x5 while a shotgun will do 10x5 bonus damage.

I added the getdamage() function to give each weapon type it's own damage amount to stop shotgun being so over powered. so you shouldn't add the damage twice. I hardcoded the damage values , you could possibly redo them as convars.
