Games should implement this behaviour with lua. It is very hard for a game to reimplement these special cases removed by the engine. It is easy for a game to make some units immune to impulse. When a unit submerges give it very large mass.

The engine should implement general behaviours with few game specific special cases. I know we have many of these behaviours but don't add more!

11:55 [LCC]jK: you should reformulate your requests and tickets to "just disable explosion based impulse for water units, but still allow lua one!"
11:56 [LCC]jK: this would get fixed, total revert of the commit won't happen

I think the engine having slightly exaggerated and unrealistic 'lolphysics' by default is something positive and I absolutely love seeing subs being blown onto shore.

Far superior to unrealistic 'nophysics', at least.

i've reverted my commit... https://github.com/spring/spring/commit ... 1dccd30907

i'm really undecided about it / don't care enough. so i prefer less c++ code :)

never thought this commit would have this effect... thanks for the feedback!

i hope thats fine for you, too, jk?!

Wouldnt changing mass on water contact have bad effects on transports?

Underwater transports?

[Forboding Angel]

Perhaps the magnification of impulse should just be toned down a bit?

Could someone tell me what I have to do to make a submarine jump out of the water?

Edit: Found it on mantis

Special case... AAAHHHHH

IRL under water explosions have much more impulse, because water can't get compressed.

Although there might be some backwards drift afterwards caused be the vacuum.

When a unit submerges give it very large mass.

O_o This fucks target priorities and transporter behavior!

Why not just use/fix push-resistance or add an attrition variable?
