Question on Unit Collision Size

Hi everyone,

Recently I created a custom Unit from scratch. Now I'm having problems setting its collision size. It used to be so simple in WC3 Editor, so I'm wondering if I can simply change a value for the collision size in SCII too.

Any help would be appreciated.

I guess I should write something of value here...

I believe you can find all collision settings under the Mover - part (you may have an other display to not see this) in the Data Editor while selecting your unit.

You can edit collision size, and some other things like priority on which unit will get scoffed aside if 2 units stands on each other.

There are two collision fields located on the unit. The first property is Movement - Inner Radius which affects the collision radius with buildings. The second property is Movement - Radius which affects the collision radius with other units.

Thanks, I found the Radius Field. Couldn't believe why I didn't find that the first time...

Anyway, a follow up question. Does anyone know what the Footprint things do? It sounds like something to do with collision size, or is it just some effect like the Demonic Footprints for the Demon Hunter in Wc3 (if you know what I'm talking about).

Footprint is used for building collision. There are two footprint fields. One for placement, and one for after they've been placed. The placement one is usually square, while the other can sometimes be rounded on the edges. Click ctrl+alt+h in the editor to view the pathing mesh in your map after you've places a few buildings.

Does the footprint work for destructibles?

Also, if I specify a footprint for a building, do I still need to modify its Movement - Radius.

Footprints works for destructibles yes.

From all my tests Footprints will override Radius, so it's not necessary to set.

As a site note: All blizzard created buildings have an appropriate Radius and a Separation Radius, so who knows; maybe it does have an obscure use even when using Footprints.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though

    I think we need to add something to the bottom of the front page that shows the Headline News forum that has a link to go to the News Forum Index so people can see there is more news. Do you guys see what I am saying, lets say you read all the articles on the front page and you get to the end and it just ends, no kind of link for MOAR!
