Any problem with making Ranged Attack while adjacent to enemy?

[Pathfinder Way]

Hi, I'm new to Pf2, trying to sort through what is actually Pf2, and what is my muddled memory of features from playing previous editions (AD&D 2e Combat & Tactics, 3.5e, Pf1, 5e).

In Pf2, is there basically no trouble with shooting, for example, a shortbow while standing next to an enemy? (Besides the longbow Volley trait.)

Most of the time, yes. Some creatures have attack of opportunity that can punish adjacent ranged attackers. That's on a case by case basis. Most don't but practicing caution is usually a good idea so players tend to avoid point blank ranged strikes. Unless you're one of the gunslinger subclasses that specialize in that.

Attack of Opportunity (AoO) ability is the only common difficulty of making a ranged Strike at an adjacent enemy. A creature with AoO ability gets a no-Multiple-Attack-Penalty melee Strike as a reaction on an opponent within reach that used a manipulate action or a move action, made a ranged attack, or left a square during a move action it’s using. Making a ranged attack against an adjacent opponent with Attack of Opportunity will hurt. This is not just about archery, because most spell attacks are ranged too.

All fighters have Attack of Opportunity and barbarians, champions, magi, and swashbuckler can gain the ability as a 6th-level feat. As for creatures, the ones the resemble fighters--usually called soldier or warrior, dressed in armor, and holding weapons in hand--typically have Attack of Opportunity. On the other hand, creatures that don't have smarts or combat training, such as animals, typically lack Attack of Opportunity.

The Step action is the standard defense against Attacks of Opportunity. Though a Step is a move action, it states an exception, "Stepping doesn't trigger reactions, such as Attacks of Opportunity, that can be triggered by move actions or upon leaving or entering a square." Thus, an archer can spend one action to Step out of reach of an enemy fighter, and then shoot safely.
