As the title says, how can we get the (key?)values of entity(s) named "something" and then modify it?
For example, we cannot make a weapon entity in hammer with 0/0 ammo. If we put "ammo" with value 0 then it spawns weapon with 20/0 ammo. So I need to edit this weapon entity named "gun_1" and make its ammo 0/0 or 1/0 according to my needs.

By cycling all entities..

for(new i = 1;i < GetMaxEntities();i++)
{
if(IsValidEntity(i))
{
new X[128];
if(GetEdictClassname(i, X, sizeof(X))){
if(StrEqual("class_name_here", X,false))
{
//Do something with that entity
//As Example SetEntPropEnt(i,Prop_Data,"m_hOwnerEntity",cl ient)....
}
}
}
}

So, class_name_here is to be replaced by, say, weapon_ak47 right? and how do I get the Property name(const char[] prop)?

Yep.

That is the SLOWER way to do it (source: benchmarked it).

The best way to do it is:

PHP Code:

int iEntity = -1;
while ((iEntity = FindEntityByClassname(iEntity, "put your classname here")) != -1)
{
// Using iEntity as the entity index, do what you need to do in here.
} 


And as for using the property name you use any of the GetEntProp functions (GetEntProp, GetEntPropString, GetEntPropFloat, GetEntPropEnt) depending on the property type (usually GetEntProp is used).

PHP Code:

int DefIndex = GetEntProp(iEntity, Prop_Send, "m_iDefinitionIndex"); 


You can find a list of netprops (property names) for each entity classname using sm_dump_datamaps and sm_dump_netprops.

Spoiler

For anyone wondering the benchmark thing, the slower code took 0.022 seconds to run whereas the faster one took 0.009 seconds.

Thanks Potato! Really useful information.
