Test attack/attack ground with vision blockers

Check if attack and attack ground can be prevented outside of an area via vision blockers. Or perhaps some other method.

So it certainly seems that vision blockers can be used. However, I am unsure how they will interact with alliances in play.

With players clustered together tighter, smart usage of alliances will probably need to be done. In such a case, there will be no enemies close enough for a player's towers to automatically target that of another. Still, they can be manually

• Attack: Check if the target unit is within the player's area. If not, cancel the attack.
• Attack Ground: Check if the target location is within the player's area. If not, cancel the attack. An issue here is the size of the AoE. If sufficiently larger, it could carry over into another player's area.
