Adjusting Physics

Adjusting Physics

Postby SpiderMack » 03 Dec 2016, 00:51

How do you adjust with visual feedback capsule, cube, sphere sizes and offsets for custom characters and models sizes ?
I have many models detailled, but collision needs to be import because it's better low poly, can i do it ?

As mentioned on the other topic, you can debug physics from the Scene setting > Debug physics checkbox.

Also custom shapes are not yet usable but something that is sorely needed to keep good performance with the physics system.
Again, we shall think on best approach and see whats possible the quickest way.

All these reports could take some days to fix but we shall focus on getting these things working.

p.s. one known buggy area of skyline Gen2 atm is cameras. They do some strange results after switching to them and running the game, so these ones we know about :)

No, physic changes values are only visible running the game, not visible changes in edit mode.
Can be usable in real game production if you adjust thousand models physics and characters, if you need to lauch game each model physic adjusting.

Temporary solution
1) import detailled mesh , don't add collision
2) import low poly collision mesh , place it at same position detailled mesh, add a full transparent material
You have detailled mesh, with low poly collision, but it's too slow to make physics for thousand models in production mode :(

Solution 2
Import low poly collision same time with hight poly from 3D file, editor will add detailled visual mesh and add Physix collisions to low poly mesh.
It works

Solution 3
If we can visualize adjust collisions in editor (no runtime game), we can add two three collision shapes to cover the detailled mesh.

Solution 4
Editor can create a low poly collision, we enter number of polygons and press button "create low poly collision"

All these reports could take some days to fix but we shall focus on getting these things working.

Yes , engine basic improved usability is lot more important than Gen2.

A work around.

Toggle Scene edit in play mode , and have physic debug check in "scene settings", you'll see physics shapes.
When you change a physic shape value and press enter, physics shape displays changes automatically.

Gen2 is the engine for all the improvements and Gen1 is being fazed out. Which is why Gen2 is more stable and has more editor features.

I think i covered in the pm, that the physics only runs in play game or animate mode ;)
