Radar jammer spell

Is there a trigger to remove minimap ability from a player/players? remove the minimap or blur it so much that its unsuable or somethin. Is there a way?

Theres nothing called minimap ability... And you cant remove, but you can replace it.

I think the most you could do trigger wise is constantly enable and apply a black mask on the entire map (as that then masks the minimap, such as through a periodic event); disable the minimap buttons; and hide all creeps on the minimap. Unless there's a black mask function for the minimap that I can't see atm.

apply black mask means fog of war? or does it actually do somethin to the minimap cause i intend to make the map such that u can see everythin but u cant see the minimap.

How do u hide all creeps on the minimap only ..which trigger?

Black Mask isn't fog of war. Fog of War is a partially visible layer that covers up areas you've previously viewed. Black Mask is a pitch black mask that prevents you from seeing all but the most basic details.

Fog of war does not black out your minimap, black mask does.

Under the "Game -" prefix You will find "hide creep icons" as well as "disable minimap buttons."

I THINK you can also trigger a player's minimap to disable terrain as well. If you can figure out how to do that, then you're in business, because you won't even need to black mask the minimap. Because essentially right then and there, you have disabled the minimap, as the minimap only lets you see: Terrain, Creeps, Previously viewed areas (that's why you can use that OR black mask) and neutral buildings/gold mines.

I actually think I did this once, but I can't remember how I did it. I can't remember if I just used the black mask feature or if I managed to lock out player control of the minimap while setting the minimap settings to basically let them view nothing.

Also, you might want to disable all your neutral buildings/gold mines from appearing on the minimap, so you'll have to do that individually with each building you use. There's an option under the unit called "shows up on minimap as:" or "minimap appearance" something like that then has a pulldown menu. Select none.

Few buildings show up on the minimap.

i cant seem 2 get it to disable the minimap well enough,those triggers hardly do anything. I gues it can be done, thanks for replyin though.

as for showing up on minimap appearance, once u do that,its set and u cant seem to trigger it otherwise. Cant trigger it with a spell

I wanted to trigger it such that the minimap becomes unsuable but u can see everything else

A really weird solution but...
Setting Stats - Hide Minimap Display in the Object Editor will completely hide a specific unit type from the minimap.
Now since you referred to this as a radar I'm assuming that's what it's supposed to be in your map so...
Make sure you hide minimap display in the object editor for all unit types you used. Then make a trigger like this (adapt the time to what you think will look nice):
Actually does look like a radar and can easily be disabled/limited since it's just a trigger. You can even import a custom minimap picture, a green radar circle kind of like on this picture.

hmm thats better than nthg i guess. Thanks 4 the idea

And you could replace the "Model - Minimap Indicator" with a custom model so you don't have the obnoxious flashing ping all the time. The problem with this is you wouldn't be able to the difference between players pinging and the radar indicators. Maybe you can customize the Flashy and Warning ping models used by the more advanced Ping With Color action, I didn't investigate that far. In fact you probably want to use the Ping With Color action so you can use different colours to indicate different players.

And of course you wouldn't want to use the exact trigger SFiliip gave, you would want to prevent the unit group from leaking.
