Hello, I'm trying to make players get random models every spawn with a percentage. So like :
50% using MODEL 1
25% using MODEL 2
25% using MODEL 3

This is easy to do like this

PHP Code:

public Action:PlayerSpawn(Handle:event, const String:name[], bool:dontBroadcast)
{
    
    ...
    
    new RandomNumber = GetRandomInt(1, 100);
    
    if (RandomNumber <= 50 && RandomNumber > 0)
    {
        SetEntityModel(client, "model_1.mdl"
    }
    
    else if (RandomNumber <= 75 && RandomNumber > 50)
    {
        SetEntityModel(client, "model_2.mdl"
    }
    
    else if (RandomNumber <= 100 && RandomNumber > 75)
    {
        SetEntityModel(client, "model_3.mdl"
    }
    
    ...
} 


But now the problem, I want to set the percentage dynamic. So like a ConVar or KeyValues can control the chances of those models. So for example like 4 models with 10%, 20%, 60%, 10% or more. (I set the max to 20)

Is this possible? If it is I'm pretty sure that I would need to use a loop. But I doesn't really know how to use loop in this kind of situation. Any help would be very appreciated

An inefficient method, but one I'm quite partial to, is to assign a "weight" to each element and throw all elements into an array. The "weight" is how many times the element is thrown into the array. Of course for your application this isn't ideal, but hey, why not!

PHP Code:

new iModels = 3;
new String:sModels[iModels][PLATFORM_MAX_PATH] = { "model1.mdl", "model2.mdl", "model3.mdl" };
new iWeights[iModels] = { 5, 14, 1 };

new Handle:g_hArray = CreateArray(64);
for(new i = 0; i < iModels; i++)
{
  for(new j = 0; j < iWeights[i]; j++)
  {
    PushArrayString(g_hArray, sModels[i]);
  }
}

new iMax = GetArraySize(g_hArray);
new iRandom = GetRandomInt(0, iMax - 1);
new String:sModel[PLATFORM_MAX_PATH];
GetArrayString(g_hArray, iRandom, sModel, sizeof(sModel));

model1 has 5/20 chance, model2 has 14/20 chance, and model 3 has 1/20 chance.

i've thought of it this way. i'm not sure if it works, as i didn't test it and my brain usually fails a lot.

#include <sourcemod>
#include <cstrike>
#include <sdktools>
#include <sdkhooks>
#include <smlib>
#include <smartdm>

#pragma semicolon 1

new maxnumber = 0;
new String:modelpath[32][64];
new modelnumber[32];

public OnPluginStart(){

	HookEvent("player_spawn", OnPlayerSpawn);
	LoadModels();

}

public OnMapStart(){

	LoadModels(true);

}

LoadModels(bool:preload = false){

	new Handle:file = OpenFile("cfg/models.txt", "rt");
	decl String:buffer[128], String:data[2][64];
	new count = 0;
	while(!IsEndOfFile(file) && ReadFileLine(file, buffer, 128)){

		ExplodeString(buffer, " ", data, 2, 64);
		maxnumber += StringToInt(data[0]);
		modelnumber[count] = maxnumber;
		strcopy(modelpath[count], 64, data[1]);
		PrecacheModel(modelpath[count], preload);
		Downloader_AddFileToDownloadsTable(modelpath[count]);
		count++;

	}
	CloseHandle(file);

}

public OnPlayerSpawn(Handle:event, const String:name[], bool:dontBroadcast){

	if(maxnumber == 0){

		return;

	}
	new random = GetRandomInt(1, maxnumber);
	for(new i = 0; i < 32; i++){

		if(random <= modelnumber[i]){

			SetEntityModel(GetClientOfUserId(GetEventInt(event,"userid")), modelpath[i]);
			break;

		}

	}
	return;

}

cfg/models.txt:

45 hatsunemiku.mdl
44 kagaminelen.mdl
1 okumurarin.mdl

the sum doesn't have to be 100, it can be anything.
edit: i forgot closing the handle. i always forget that.
edit2: why the hell modelnumber was defined as a string?

Thank you for the both reply. I've learned something today
