1.) It works like this: Ped handle, entity handle, horse handle, speed. It is available in RAGE Plugin Hook so no need to invoke it yourself.
2.) I am not sure if you can attach/place it there with a native. Maybe it is easiest to attach it to the wagon?
Very nice, might even solve your problem a bit easier: Use any weapon to determine whether they got first (param 2). If so, then make sure that param = 1 is false, so they have not been damaged by any melee weapon. Should save you from looping through all weapons.
I wonder if some peds just do not have these bones (or use different names). It's hard to say without the models. Can you get valid positions for the forearm bone on the other peds?
We have no record of your LCPDFR being linked, could you please try again? If you are still having issues, please PM me on LCPDFR.com from your account there.
I just tested it myself and it works fine, but due to an API change you need to change one line of code. Make sure to use the latest SDK dll in your "Dependencies" folder (it's from January 24). Once you have updated it, line 35 should throw an error when trying to compile. Change it to "if (Input.WasKeyJustPressed(Keys.G))" and it should then compile just fine. Copy the updated plugin into the C#Plugins folder.
Also please note that you are not supposed to copy the SDK DLL into the game folder or the C#Plugins folder. You just need it in your project folder.
Yeah hooks can co-exist fine just like on GTA V, that's not a problem. Does your logfile reveal anything? Perhaps some files are missing causing it to crash.
The native hash is 049D5C615BD38BAD but the arguments are two structures, so it's a bit more effort to get it working. RAGE Plugin Hook has that function wrapped for you in C#, so that might be the easier way.
RAGE Plugin Hook has a function to print help and it also works with any .NET language, so perhaps you can give that a try. We have a tutorial here:
