When I get into the game, I'm able to fire a weapon or sound my siren or horn in any vehicle, but I am not able to do any melee attacks. Whether it be with a bat, knife, or fists, I can't attack. I click to punch, and Niko just stands there and does nothing, but when I pull a gun, I'm able to play normally. Please help.

What version of GTA IV do you have and is it a legitimate copy of the game?

What mods are you running / what changes have you made to your game?

 

 

I am running patch 1.0.7.0, it is a legal copy. I have Deadly Wrecks, Fuel Script, LessOvertake, TrafficFlow, Tow Service, LCPDFR, and modded weapons, weapon sounds, non-ELS vehicles, and modded Peds.

Right in that case what I would recommend doing is removing all of your mods and try to see if it works then, if it does then you can go ahead and slowly install each mod again one at a time.

 

If it doesn't fix it come back and say so and I will have another think as to what it might be.

You can always get a clean installation of gta IV, then re-mod one by one. The reason I say mod one by one is because that way you can know which mod is causing the issue.

I agree with Luke on this. I just want to add: More Scripts = More Problems. 

 

@Darkray347, Wasn't that exactly what Luke said... just worded differently? Lol.
