Screen shake onDamage possible?

I'm just curious whether it is possible to add a minor screenshake upon taking damage or landing critical hits. I've been messing around with a few scripts, but I'm unable to get any solid results.

onDealDamage = function(self, champion, damage)
party:shakeCamera(0.5, 0.3)
party:playScreenEffect("damage_screen")
something along this line ?

That basically the same to what I'm using. I'm just not sure what to add for (self, champion, damage). Especially damage.

you don't need to add anything if you don't want to, they're just useful options

I would consider doing something like the following in order to have the screen shake whenever the player takes damage (it's a tad harder for monsters, as you have to hook into every monster I believe).
You have to modify the default behaviour when the player takes damage by adding a party hook - these let you have custom lua functions, that you define, called when certain things happen to the party. Either add the following to init.lua or add it to a new file, party.lua and then add an import line to your init file to link in the new file.
Simple Shake Code (based on @Skugasveinn's script).
Code: Select all
cloneObject{
name = "party",
baseObject = "party",
onDamage = function(champion, damage, damType)
party:shakeCamera(0.5, 0.3);
party:playScreenEffect("damage_screen");
return true;
end,
}
Slightly More Complex Shake Code (shakes more on more damage).
The function bit defines your custom logic - champion, damage and damType are parameters passed to your code from the game engine. Here we use those to shake the screen more if you take a higher proportion of damage.
Code: Select all
cloneObject{
name = "party",
baseObject = "party",
onDamage = function(champion, damage, damType)
local intensity = damage / champion:getStatMax("health");
party:shakeCamera(intensity, 0.3);
party:playScreenEffect("damage_screen");
return true;
end,
}

That LUA works wonderfully. Much thanks, John.

Those are pretty straightforward and clear. I love messing with simple math in functions, it can get clever very fast, good stuff.
You can also leave off the "return true" line. It always returns true as a default, you only need to put something if you want it to "return false" or perhaps return some other value (rare/advanced).
Code: Select all
cloneObject{
name = "party",
baseObject = "party",
onDamage = function(champion, damage, damType)
party:shakeCamera(0.5, 0.3);
party:playScreenEffect("damage_screen");
end,
}
Code: Select all
cloneObject{
name = "party",
baseObject = "party",
onDamage = function(champion, damage, damType)
local intensity = damage / champion:getStatMax("health");
party:shakeCamera(intensity, 0.3);
party:playScreenEffect("damage_screen");
end,
}
