Infantry get stuck behind tanks and trucks in Spring 1944

[Godde]

Infantry are unable to push trucks and tanks in Spring 1944.
Infantry tries to move onto the position of the truck as they path through it. They might keep humping the truck forever unless new orders are given.
Infantry have a footprint of 1x1.
How can this be solved?



This happens in both Spring 91.0 and in the latest test version as well(spring 91.0.1-1318-g7fbf6d7)

shit happened with gundam and I was forced to enable pushing. Some point in time the units started doing this. I always assumed it was part of some WIP code. Does this still happen in 0.92?

[Godde]

Yes it does happen in the latest test version which will become 92.0

No noticeable improvement.

Only the truck is pushResistant, the infantry should not be.

[smoth]

correct, because the truck is push resistant it doesn't move for the infantry. the infantry don't care, they keep trying to push the truck to go through. It isn't the trucks fault, it is the infantry.

it isn't only the infantry it is any unit trying to move past a push resistant unit. The current pathing model doesn't work without all units having push resistant off.

Any updates kloot? I am still seeing units trying to move through one another.

With which engine build(s)?

Note: units will always* try to path through units because it is assumed that the collision code removes the need for one party to go around the other. When one unit in a colliding pair is push-resistant, this works less well (but still acceptably in the latest builds) and a solution would be to make the pathfinder treat such units as structures instead. Collisions between two push-resistant units are a total pain to support however, and that is why they no longer behave like in the 0.82.* days (as you found out: http://springrts.com/phpbb/viewtopic.php?f=14&t=29782)

* this tendency can be controlled with the default pathfinder on a per-MoveDef basis, see http://springrts.com/wiki/Movedefs.lua#speedModMults ('mobileIdleMult' is probably of the most interest to you)

so when pushing happens, are we always going to get the sliding or is that going to be addressed in the future?
