If you are adjacent to an opposing character (barring the Sharpshooter Ability), you cannot make a ranged attack against that character. I assume this is not true with walls, blocking terrain, and objects, correct?

In general you must be adjacent to your target to make a close combat attack, (Pg 9 of 2011 Core Rules - A close combat action can be given to a character to activate a close combat attack that targets an adjacent opposing character.) if a character is in the same space as an object, that character could not make a close combat attack on the object?

sure they can. I'm sure someone can and will post the printed reason. I can't at the moment.

I am trying to find the "printed reason"

Page 19 of the rules:

DESTROYING OBJECTS
Objects can be destroyed using the rules for destroying a square of blocking terrain (see p. 13). A character in the same square as an object does not take damage when the object is destroyed. An attacker can’t target both a character and an object with the same attack. A destroyed object is removed from the game and does not cause a debris marker to be placed.


So then on page 13:

DESTROYING BLOCKING TERRAIN
A square of blocking terrain can be destroyed by a single attack that deals at least 3 damage. When a character attacks blocking terrain, the attack automatically succeeds. A close combat attack can be used to destroy a square of blocking terrain adjacent to the attacker. A ranged combat attack can be used to destroy a square of blocking terrain by drawing a line of fire to the center of the square of blocking terrain; the line of fire is not blocked by the target square in this instance.


A character is not adjacent to the square it occupies. This includes not being adajcent to an object in that same square. And if you are not adjacent, you can't destroy it with a close combat attack.

thank you.

Thanks! Am I correct on the ranged attack?

Page 11:

RANGED COMBAT
Ranged combat represents attacks that take place over distance, such as thrown bombs, repulsor rays, machine guns, energy blasts, and psionic attacks.
Every character has a range value printed on its base. This is the maximum number of squares that a character’s ranged combat attack can reach. If the range value is greater than 0 and your character is not adjacent to an opposing character, then your character can make a ranged combat attack. A character can attack in any direction, regardless of the direction it is facing.




I am not 100% sure what exactly you where trying to ask with your ranged combat question, but an adjacent opposing character will prevent ranged combat. Period. Even if your character was trying to shoot a wall or object.

Now if you were asking if objects could somehow prevent ranged combat, I will tentatively answer "No, they can't prevent ranged combat because they are not opposing characters" but I would also ask you to rephrase the question, please.

Rephrased - Wall/Barrier/Object Q's
If you are adjacent to an opposing object, wall, or blocking terrain, (barring the Sharpshooter Ability), can you make a ranged attack against that element? (Can Jack Flag who is adjacent to a wall make a ranged combat attack against that wall using a character with enhancement to make his damage 3.) I understand you cannot make a ranged combat attack against an adjacent character because there is a rule barring you from doing that.

I can find no rule barring me from making a ranged combat attack against one of those game elements, but that does not mean it does not exist. I have someone telling me you cannot, because it is treated as an "opposing adjacent character" which no rule that I can find says to treat these elements as such.

They are not opposing characters, so it's fine to make a ranged combat attack.
