[Guide] Object Placer

[Bazsi37]

Dynamic Placers

This guide will cover how to use the Dynamic Object Placer (DagDP) entities. These allow you to randomly place SOME RI on pre-defined surface areas/terrain.

UNSUPPORTED RI:

• Buildings:
  

• Most vegetation:

Use of notepad++ is highly recommended.

I used the test blk made by one of the devs as a basis of this guide: dagdp_tesst.blk.txt (4.1 KB)

The goal in this guide will be to generate cacti on this area:

We have several entities related to object placer:

To simplify the process, we will use a “complex” entity also used in the test mission and edit that. Read the comments and the in-editor remarks.

entity{
  _template:t="dagdp_rule+dagdp_placer_heightmap+dagdp_object_group_riex"
  dagdp__name:t="test_rule_shrooms" // can be named anything.
  dagdp__skip_chance:r=0.5
  dagdp__density:r=4.5938

  "dagdp__biomes:list<i>"{
    index:i=22  //biome index. We have no info about what biome belongs to which ID. 
    index:i=27 // Yes you need to guess until it works...
  }

  "dagdp__assets:object"{ //add/remove Ri from RI list here. Not all RI will work!

    "boletus_edulis_a:object"{ // RI name
      scale:p2=1.1, 0.7 //RI scale. First number must be bigger than second number.
      rot_x:p2=0.0, 10.0 //RI rotation on X axis presumably randomly between the 2 values.
      rot_z:p2=0.0, 10.0 // RI rotation on Z axis same as above
    }

    "boletus_edulis_b:object"{
      scale:p2=2.0, 1.0
      rot_x:p2=0.0, 20.0
      rot_z:p2=0.0, 20.0
    }

    "boletus_edulis_c:object"{
      weight:r=5.0
      scale:p2=3.0, 2.0
      rot_x:p2=0.0, 30.0
      rot_z:p2=0.0, 30.0
    }
  }
}

By default this will place mushrooms on certain types of desert terrain:

As you can see mushrooms are only placed on smooth sand, but not on “wavy” ones.

Let’s replace the values with cacti, and save the scene:

entity{
  _template:t="dagdp_rule+dagdp_placer_heightmap+dagdp_object_group_riex"
  dagdp__name:t="test_rule_shrooms"
  dagdp__skip_chance:r=0.5
  dagdp__density:r=0.01

  "dagdp__biomes:list<i>"{
    index:i=22
    index:i=27
  }

  "dagdp__assets:object"{

    "african_cactus_e_b:object"{
      scale:p2=1.1, 0.7
      rot_x:p2=0.0, 10.0
      rot_z:p2=0.0, 10.0
    }
	"african_cactus_a:object"{
      scale:p2=1.1, 0.7
      rot_x:p2=0.0, 10.0
      rot_z:p2=0.0, 10.0
    }
	"african_cactus_b_a:object"{
      scale:p2=1.1, 0.7
      rot_x:p2=0.0, 10.0
      rot_z:p2=0.0, 10.0
    }
	"african_cactus_f:object"{
      scale:p2=1.1, 0.7
      rot_x:p2=0.0, 10.0
      rot_z:p2=0.0, 10.0
    }
	"african_cactus_g:object"{
      scale:p2=1.1, 0.7
      rot_x:p2=0.0, 10.0
      rot_z:p2=0.0, 10.0
    }
  }
}

Now we can fine-tune our placer in the editor:

And done. You can get info of each parameter in-editor, i won’t explain it.

thanks for the findings and effort

[Bazsi37]

@Enginya Could we perhaps get a spreadsheet or something, so that we don’t have to guess the IDs for the biomes? I saw biome_querry entities and a copule biome_xxx commands, but none of them helps unfortunetly.

@Bazsi37

dagdp__biomes

Have you tried to leave dagdp__biomes empty as tooltip suggests?

[Bazsi37]

But what if i only want to “paint” on burnt_ground or grassland for example?

[Enginya]

Then report to moderators, helpers or https://community.gaijin.net/ to ask related to write manual

Those biomes are really deeply hidden into terrain types definitions, so I can’t even find them easily

You can also peek into blk files in existing scenes for dagdp__biomes and ri_gpu_object__biom_indexes
