Re: [CSGO]SDKHooks: Instruction contained invalid parameter

Are you using a compiler from an official build of SM?

Yes, but where is the point of your question, this problem is not occurred by the compiler?

Re: [CSGO]SDKHooks: Instruction contained invalid parameter

SM does checks on the compiled plugin code to see that some things make sense. The error means one of those checks failed. Either the compiler output something it shouldn't have or the check itself is wrong. A bug in the compiler is more likely, especially if you're running a custom modified version.

Can you post the exact versions of SM and compiler that result in seeing the error? Can you also post a copy of your plugin that you compiled?

Re: [CSGO]SDKHooks: Instruction contained invalid parameter

Currently, I found the problem in all of my functions of include but I don't get it:

Try to explain where is a different between "IsValidPlayer" and "IsValidEntity", valid ent will work correctly.
In the scope of SDKHooks "victim" is a client index same as "attacker", why then I have got "Instruction contained invalid parameter" error.

Re: [CSGO]SDKHooks: Instruction contained invalid parameter

We can not help you if you do not provide what was asked.

OK, from scratch: I have the plugin to prevent Team killing with nades exception.
In the current state, plugin works.

But if I will use some functionality from maincore lib, the plugin will crash without any exception.
E.G: "IsValidClient" instead sm "IsValidEntity".

Re: [CSGO]SDKHooks: Instruction contained invalid parameter

Ok I found the problem:

PHP Code:


		
			
OnTakeDamage(int victim, int &attacker, int &inflictor, float &damage, int &damagetype)

Client indexing started from 1 to MaxClients but in this case int &attacker is always 0.

any idea how to fix it?

Re: [CSGO]SDKHooks: Instruction contained invalid parameter

0 is perfectly valid for attacker - it indicates damage done by the world (such as falling damage).

OK, then how to determinate who directly was shooting to the victim?
