[Trigger] Terrain type check

[Kercyn]

I want to create an ability that grants some bonuses while the hero in within a terrain type (snow, im my case). When the ability is cast, the hero covers an area in snow (Point-blank AoE and similar to blight creation) and gets IAS, MS and evasion. Those bonuses last while he stands in snow (I would like the snow to "melt" after x seconds, resetting the tiles) and disappear if he moves away.

I know that terrain-type checking is doable (eeve! TD, Pyramid escape etc) and so is tile resetting (if you've played "Slide, Ninja, slide", you'll propably know there is a skill called "Thaw". That skill creates a small area of blight - I think - at target point for a few seconds. Once the effect ends, the blighted tiles become snowy again), but I can't think how to implement it.

Last but not least, I would like to know if I can create a weather effect on the area the spell is cast and remove it once the spell duration ends.

A big "thank you", a free /hug and +rep to anyone who helps me!

Check Terrain:

• Conditions
  • (Terrain type at (Your Location) Equal to Lordaeron Winter/Northrend/Icecrown Glacier - Snow

Tile Resetting (NON MUI/MPI):

• Actions
  • Set Point = (Your Location)
  • Set TerrainType = (Terrain type at Point)
  • Environment - Change terrain type at Point to Lordaeron Winter/Northrend/Icecrown Glacier - Snow using variation -1 in an area of size 1 and shape Circle
  • Wait X seconds
  • Environment - Change terrain type at Point to TerrainType using variation -1 in an area of size 1 and shape Circle
  • Custom script: call RemoveLocation(udg_Point)

To cover a bigger area you need to make the variable "TerrainType" an array variable and make it store the terrain type of more locations.

Weather Effect (NON MUI/MPI):

• Actions
  • Set Point = (Your Location)
  • Set Area = (Region centered at Point with size (WIDTH, HEIGHT))
  • Environment - Create at Area the weather effect (Some Effect)
  • Set WeatherEffect = (Last created weather effect)
  • Wait X seconds
  • Environment - Remove WeatherEffect
  • Custom script: call RemoveLocation(udg_Point)
  • Custom script: call RemoveRect(udg_Area)

Seems to work ^^ I'll try to make it MPI and I will post it here.
Thanks!
