ZDoom

I'm looking to be able to dynamically adjust the player's view height based on whether they are aiming down the sights of a rifle or not. Is this possible?

You can change the viewheight property on the playerpawn, but I haven't checked how exactly it would interact with crouching.

EDIT: you may need to multiply the height by player.crouchfactor or something similar.

Can you do it dynamically based of in-game input?

Try putting in your playerpawn's Tick() somewhere and give it a try:
A correction to my previous post: best to only manipulate "player.viewheight" (a property of the player thinker) not "viewheight" (a property of the player pawn) since that's the way it's done in the crouching code.
