Summary

0003070: Laser weapons can't target enemies too close to allied units

Description

As the title says:

- you have a building with a certain groundplate and hitsphere size
- there is an enemy unit either "on the groundplate" of your building or the hitspeheres of the building and the unit are intersecting
- other allied units are not able to target and shoot the enemy unit with LaserCannon/Beamlaser or Lightning weapons (I only tested those)
- Cannon type weapons can target the enemy unit though

Tested for ZeroK and The Cursed (having removed all gadgets before) so far. This is very exploitable (e.g. raiders vs. LLT/HLTs)

Additional Information

no "avoid anything" tags used in this example:

LASER = {
      name = [[Commander Laser]],
      areaOfEffect = 12,
      beamlaser = 1,
      beamTime = 0.1,
      coreThickness = 0.5,
      craterBoost = 0,
      craterMult = 0,

      damage = {
        default = 15.5,
        subs = 0.8,
      },

      duration = 0.11,
      edgeEffectiveness = 0.99,
      explosionGenerator = [[custom:flash1blue]],
      fireStarter = 70,
      impactOnly = true,
      impulseBoost = 0,
      impulseFactor = 0.4,
      interceptedByShieldType = 1,
      largeBeamLaser = true,
      laserFlareSize = 3,
      minIntensity = 1,
      range = 300,
      reloadtime = 0.11,
      rgbColor = [[0 1 1]],
      soundStart = [[weapon/laser/pulse_laser3]],
      soundTrigger = true,
      targetMoveError = 0.05,
      texture1 = [[largelaser]],
      texture2 = [[flare]],
      texture3 = [[flare]],
      texture4 = [[smallflare]],
      thickness = 3,
      tolerance = 10000,
      turret = true,
      weaponType = [[BeamLaser]],
      weaponVelocity = 900,
    },

(0008965) Kloot (developer) 2012-07-12 17:02	no feedback --> assuming avoidFriendly helped

(0008966) azaremoth (reporter) 2012-07-12 19:37	Of course "avoidFriendly = false" helps - but that does not realy solve the problem. You can`t make all weapons passing through other units/buildings/etc. if it does not fit your game's design. What helped for the Cursed was setting "collisionVolumeTest = 0" for all units (and making all weaponspeeds <=900).

(0008968) Kloot (developer) 2012-07-12 21:57	I know, but it's also not trivial to prevent units from ever getting so close to a building that they are shielded from hits by its collision volume (especially with custom shapes). You might have to look at gadget workarounds if avoidFriendly and/or collideFriendly aren't sufficient in combination.
