I was to lazy to look around to make it, but

Precision by heat = ?
Please do not answer if you dont know what you are going to talk about.

I assume you refer to the traits of the Plasma Repeater. I'm not entirely certain that there is a way to directly link heat with precision, but you can make it so that a weapon fires more accurately the longer you hold the trigger. If you toyed around with the values, you could probably make it so that the accuracy increased at roughly the same rate as heat buildup, and lost accuracy at a similar rate to the weapon's cooldown.

I thought someone already accomplished this sort of thing? At least, I am pretty sure I saw someone who made the reticle like in halo reach show the bounds of precision getting larger and less precise, but it did not show if the actual accuracy went down.

It's in the weapon tag. LOOK in the weapon tag.

This.

^^
lolol, well i know where to set the options, and i was thinking to something WAY MORE complicated, to have an accuracy difference even when not keep pressing fire button (semi auto), like for the halo 2 M6C. I'm looking for a direct link

How do you get it to vent off heat?

When the weapon dosen't fire.

Do you mean like in Reach?
Custom anims.

LOL NO. odx he meant.

spread is determined by how long you hold the input down

this would not work

^True this

Nvm i give up about help.
