not engine ... spherepole just doesn't auto attack buildings, must be some zk lua ... spawn an unit with a weapon and see spherepole attacking it spawn an building w/o weapon -> won't move at all (even on fire at will + roam) |
|
|
Spherepole does not auto attack Solars because they are a bad target. That is just using noChaseCategories. If you spawn a spherepole near armfusion and set to roam it will go and attack it. If you think that is relevant to the report then you misunderstand the bug. The bug is that when given an attack command it will often stop before it is in range. Target acquisition is not what the report is about. I have reproduced this with luarules and luaui disabled. |

Is this a recently introduced bug ? If so, in which version/commit was this bug introduced ? |
|
|
I do not think it is recent. |
|
|
Same thing for The Cursed (comapre http://azaremoth.square7.ch/img/refusal_to_attack.jpg). The bug was already included 99.0-RC3. Maybe even before. I do not know. |

|
edit: wrong issue, sorry. |

I have bisected the bug and found that it is actually a recent bug. For some reason the bug seems to have become worse recently but I have not done a good test to determine this. Works in 97.0.1-363-g81eb79c https://github.com/spring/spring/commit/81eb79ceaa785a1bcf2ba645b0d5469f883e85f2 Broken in 97.0.1-372-g41e3c42 https://github.com/spring/spring/commit/41e3c42f77ff8787488631bccaae3409bf36f13c There are a few pathfinding changes between those two versions but I don't have any intermediate builds. |

|
This still occurs most of the time even though https://springrts.com/mantis/view.php?id=4778 appears fixed for ground units. |
|
|
This bug seems to only occur when the target of the attack is on impassible terrain which is covered by an enemy structure. I tested with attack ground commands to underneath an enemy structure as well as attack commands directly on the structure. Perhaps the pathfinder stops the unit prematurely because the target cannot be reached. Perhaps it is something to do with targeting. I don't know. The bug with both attack ground and unit targeting is demonstrated in '98.0.1-706-gaa3e0e2 ground target' I would like to know that jK isn't ignoring this issue. I worry because his only post was to dismiss the bug because the unit had a noChaseCategory. |

seems to be fixed by https://github.com/spring/spring/commit/47bf190a1801a0490811bfd9c58ba0c4b2ac13b6 duno how and why - i thought I only fixed ground attack -, but you don't question gifts that fall from the sky ;) |
