[SCRIPT] Item on entetie

[Quotentote]

haiiii there again

my 3rd level is on the way \o/
now i wanna make following script sequence:

you have a dagger and you need to use it on a ritual prisoner to get a key. i want this to happen:
small 'flashszene' (white screen/some screams), prisoner doesnt move anymore, key appears and some blood streams out of his wound.

how do i have to write that script?

is it an area script which make the other things active/inactive when i touch the area with the dagger?

You'll want to utilize AddUseItemCallback in conjunction with CreateParticleSystemAtEntity, SetEntityActive, StartEffectFlash, SetPropStaticPhysics, SetEntityActive, and PlaySoundAtEntity.
