Other Screen Overlay?

Is there a way to make items cause a screen overlay? For example, if I wanted a drug item to cause the screen to be blurry for 5 minutes, would that be possible? Things like blurred vision, color tints, that sort of thing.

 

Thanks, I'll play around with this and see what happens

 

Here is an example of the code to a DRUG mod. When you use a drug it changes your screenspace.

However Im sure you can interpolate this into something.
Basically your code will be like

Function(player, EntityItem)
onplayeruse(Enable screenspace effect for curtime 5 mins or something. I'm very nooby with coding but can interpret it okay.

 

So I'm not entirely sure what to do with these values? I'm not very proficient with lua, so this is kind of a leap in difficulty for me.

 

Look at the base alcohol scripts in your schema for an example?

That's what I've found regarding alcohol, but it doesn't mean anything to me. If there's someone that's willing to sit down with me and help me out, that'd be appreciated.
