Enemy Creeps Get stuck on wall
---------------------------------------------------------------------------------------------------------------------

Im making a castle defence type survival game. Each player gets a hero and they have to survive in a fort. The monsters are supposed to attack these 2 barricades and the players repair it. Anyway, often if a player is in a particular position, the monsters will try to attack a player but get stuck on impassible terrain. How can i fix this so that the monsters go for the wall first even if they are getting attacked.


Ive tryed making it so the enemy can only attack walls then when the wall is down they are transformed into enemies that can attack anything. The problem is that if the player goes outside of the fort, the enemy wont attack them, making the whole thing pointless.

Is there some sort of ai i could create to make them go for walls first and not become stupid idiots and get stuck when being attacked ???

Any suggestions would be great

In many games the important things must come first, then the less important ones:
1 Units and heroes.
2 Attacking buildings.
3 Buildings.

I believe it's called ''Priority'' in the Object Editor.

Just make it so when they enter a region close to the barricades they are ordered to attack it, very simple.

that doesnt work but i fixed the problem anyway by making the walls do slight missile damage.
