Behavior adding hit-scan support to elements.
Behavior supports using one or more collider collision tests to do one or more hit scans for example to check for weapon projectile impacts. Hit scans are done once then the result can be examine. To use this behavior add ECBehaviorCollider then this behavior. The collider is used to carry the collision tests.
To start a series of hit-scans call one of the start() methods to set up the hit-scans. You can set up the hit-scans manually or use the convenience methods to set up hit-scans matching typical use cases. Starting hit scans has to be done during think() time.
After setting up hit scans during think() the physics module carries out the desired collision tests. The result can be evaluated during the following postThink() or the the next think() call.
A typical scenario is a projectile weapon triggered by the actor. The weapon element has the ECBehaviorHitScan. When the player triggers the weapon the hit-scan is started() in the think() phase and the hits evaluated in the postThink() phase.
class MyWeaponClass extends BehaviorElementClass
public var ECBehaviorCollider collider
public var ECBehaviorHitScan hitScan
collider = ECBehaviorCollider.
new(this, null)
hitScan = ECBehaviorHitScan.
new(this, collider)
end
end
class MyPlayerAction extends BAAFirstPerson
end
public var bool doesFireWeapon
func void think(float elapsed)
super.think(elapsed)
if doesPlayerFireWeapon()
var BehaviorElement weapon = getPlayerWeapon()
ECBehaviorHitScan.getInstanceIn(weapon).start(...)
doesFireWeapon = true
end
end
func void postThink(float elapsed)
super.postThink(elapsed)
if doesFireWeapon
doesFireWeapon = false
var BehaviorElement weapon = getPlayerWeapon()
ECBehaviorHitScan.getInstanceIn(weapon).forEachHit(block ColliderCollisionTest test
if test.hitCollider(0) != null
var BehaviorElement target = test.hitCollider(0).getOwner() cast BehaviorElement
end
end)
end
end
end
ECBehaviorHitScan new(BehaviorElementClass eclass, ECBehaviorCollider collider, ECBehaviorComponent component)
Create behavior element class.
ECComposeCollisionFilter getCollisionFilter()
Collision filter for AI collider.
Another possibility is to create a behavior attached to the weapon element doing the same. This moves the weapon hit and damage logic to a behavior with the actor only triggering the behavior and having nothing to do with it.
