Description

Describe the bug When placing a structure you see a placeholder on where to build it. Moving the mouse around causes the placeholder to move as expected. However, on certain sloped angles the placeholder has some unexpected and unwanted behavior. Attached a video showcasing the behavior and a screenshot on what area to move the mouse.

To Reproduce Steps to reproduce the behavior:

  1. Boot the game and start a fresh alpha campaign (do not move your viewpoint, otherwise the marked spot in the screenshot does not work).
  2. Select the radar tower from the build menu (tho I'm sure other buildings do work too).
  3. Move your cursor (without moving your viewpoint) in the marked area.
  4. Enjoy.

Expected behavior To properly locate the position of the placeholder structure (tho the structure, when green, gets placed on the shown position).

Your System:

  • OS: Windows 10
  • Game version: 4.0.0-beta1

Contributor guide

Research direction
Investigate the structure placement code, particularly the function that computes placeholder position on slopes. Look for raycasting or terrain height sampling logic that might misbehave on certain angles.
