@Realspawn :
You can find code examples about physics without some physic engine , just do a Google search ?

@Sivan :
That's great (it could be a good terrain for some MechWarrior game also).

...and 15 grass and 8 shrub sprites (sorry for flooding the forum):

Looks good.

Have you put some LOD or distance check for grass and shrub display ?

yes.

but grass sprites are mainly okay for pro users. 80% of them are clipped at lod0 distance, and the remaingings at lod1. I decreased their resolution but still performance eaters in large quantity. this is why the grass model category exists (I will add new models soon to them too), they work faster.

shrubs sprites consist of a group of _x3 sprites, you can define the quantity from 1 to 5 resulting in max 15 sprites per shrub. they have a special lod clipping, the first sprite is clipped at lod2, the second at lod1, all the others at lod0 distance, thus they can be used effectively due to my experiences, but they are mainly for fast design, models can be nicer and more fine tuned.

You should make sprites more little no ?
The character seems tiny ?
And if they are too big, with immobile units passing throught them, it could look weird until you add physic movement of plants ?

I disagree, I think it looks more natural... I despise these games that ... well for some reason people think lawns got mowed in medival times or somethings???

please don't forget, it's just an editor screenshot, not a game. things are approx. in good scale, but there is a scale slider. maybe hard to see on this image the 3d distances... I decreased sprite resolutions today afternoon, and it has a sensible effect on speed.

shrubs are not passable, I mean the sprites itself are passable, but each plant gets a collider entity, by default a cube, but if you load it in your game you can change it by script easily to any shape.

in my pathfinder, what I plan to adapt to more game types, heavy units (like vehicles or tanks) are already set to be able to go through shrubs, while infantry and cavalry are unable. once I need to implement smoothed vehicle movement (I have the reference material for it that suits my system)...

sivan@ man, to be honest, I was amazed.. and if not that guard model on the middle of the screen, making his was throw the fields.. I could never believe that this is Acknex... Great work dude.

thanks, but they are just free stuff from nobiax.deviantart.com I spent some time with organizing and converting his works to my needs. simply better than the loopix collection, and totally free.
I'm going to add some models with his nice textures, better trees than the current ones, and other plants, rocks, all having lods etc.

the guard model is a 3dgs standard reference object, I will use it forever if I have time I will rig it to add mocap skeleton animations to it, I think it would be a big mistake to make it nicer

+1 great work love it!
