Hello.
need help in creating a flying unit, in fact - the flying tank.
I will be grateful if someone would write a part of code or tell what flags should be used for this.
PS: want create Battle Cruiser from Starcraft

I'm pretty sure you could do this just by following the
Modding Tutorial, then changing individual bits of code to suit your needs.

saw this tutorial but did not understand which parameter is responsible for flight
can you tell? not very good with English

There's no parameter to control flight, you simulate it by not putting a collision box.

I understand this, i'm working in a "blood-steam", and i can't make this "unit" fly, i have a problem with collision with entities.
I need this unit without collisions, like a fly unit (the command of blood-steam isn't configured yet, but is the same)
basically is a unit without collision_box and without collision_mask.

I noticed when I started updating the wiki tutorial to v11 that simply leaving out the collision_box didn't work (it still collided). Adding an empty collision mask property via
worked (without the collision_box, I expect it would work even with a collision_box specified though). I haven't gotten around to figuring out exactly how the new car animation works though so that's really the major delay on the tutorial update.

Ok, i tried with
Code: Select all
collision_mask = { "not-colliding-with-itself", "water-tile" }
this don't work (i think this should work), and work fine with
Code: Select all
collision_mask = { "not-colliding-with-itself" }
I think the flying tank is similar.
Thank you and welcome back FreeER

I've done a bit of testing around.
What kovarex wrote on the wiki:
collision_mask
type: Types/CollisionMask
Default: Depends on Entity type
Two entities can collide only if they share a layer from the collision mask.
should be taken literally. The presence of "water-tile" doesn't mean entity will collide with water, it means it will collide with
any other entity having that layer.
Having either "water-tile" in car mask makes it bump into transport belts. I presume that umodded car can't get in the water and collides with buildings because of "player-layer", while belt indeed has the "water-tile".
"not-colliding-with-itself" disables collisions with entities of the same
type i.e. car will pass through tank.
"not-colliding-with-itself"-only or empty collision mask will allow you to drive out of the map borders into the empty blackness of cosmos.

Thank you very much, it's helped. whether it is possible to make what unit moved above the trees and, like robots, could be attacked only range-attack.

Flying robots can be attacked by melee units.
But they probably do have the collision mask and fly around because their collision box is zero.
See if your flying tank gets attacked at all.
edit: oh it will.

And zero sized tank still collides with trees which collision box covers the center of tank.
edit: oh damn, that was meant to be edit.

I didn't see this, seems I was not first one to make flying unit help post. mayhaps a mod can merge the 2 threads.
anyways take a look at the comments in the entity file for zoomer they will save you trial and error time
as for proper flying without collision:
collision_box = {{0, 0}, {0, 0}}, -- still leaves a 1 pixel collisional zone
collision_mask = {}, -- never collide, needs this to be able to 'drive' without hitting anything
until render layer is read by all types, it will still look like it goes behind trees and buildings

Would just like to say, it would be so useful to have render_layer working for all entities.

i'm using this for my flying units.
Code: Select all
collision_box = nil
collision_mask = { "not-colliding-with-itself" }
but can use
Code: Select all
collision_box = nil
collision_mask = {}
Or other
collision_mask
Collision_mask works with collision_box = nil
I hope this be helpful.
NOTE: I don't know why, transport belts aren't in object-layer, i can't do a unit fly over it
