Point with character controller

[Rick]

Has anyone gotten the Point function to work with a character controller? I have the following call that gets hit once (flags prevent it from getting hit after that) and it doesn't rotate at all.

 

-- where this script is attached to a character model that has the character controller set for it

self.entity:Point(self.pointAtEntity, 1, 500)

character controllers need to use setinput to rotate.

 

see thread here

You can use Math::ATan2 to figure out the correct angle from the difference between the two entity positions.

I have the following attached to the character but it doesn't work.

 

the pos parameter is the entity to point at

 

function Script:FaceEntity(pos2)
local pos1 = self.entity:GetPosition(true)
local v = Vec2()

v.y = pos1.x - pos2.x
v.x = pos1.z - pos2.z

local angle = Math:ATan2(v.y, v.x)
self.entity:SetRotation(0, angle, 0)
end

you are still not using SetInput...

[Rick]

Dammnit I don't want to use SetInput

 

This still didn't seem to work when I changed it to:

 

function Script:FaceEntity(pos2)
local pos1 = self.entity:GetPosition(true)
local v = Vec2()

v.y = pos1.x - pos2.x
v.x = pos1.z - pos2.z

local angle = Math:ATan2(v.y, v.x)
self.entity:SetInput(angle, 0)
end

 

Note that my game is a point and click so I don't call SetInput() like in a fps or third person game moving with the keyboard. It's all GoToPoint() driven.

I thought you hated point-n-clicks?

 

In any case, what about it doesn't work? Is it not returning the right angle? And wouldn't you still have to use SetInput() to move your character to the 'GoToPoint'?

 

In LE2, I used essentially the same setup:

function PerfectAngle(pos1,pos2)
  local dx, dz
  dx = pos1.x - pos2.x
  dz = pos1.z - pos2.z
  return math.deg(math.atan2(-dx,dz))
end
...

perfectangle = PerfectAngle(gotohere,player.position)
angle=IncAngle(perfectangle,angle,5/AppSpeed())
...
...
player:Update(angle,move,0,0,500,1,0)

[Rick]

And wouldn't you still have to use SetInput() to move your character to the 'GoToPoint'?

 

Nope. GoToPoint() is magic

 

Had some code structure issues but it's "working". Right now he points in the complete opposite direction. Getting closer.

 

 

[edit]

Got it. Thanks for the code mac.

yeah i dont use that... it feels dirty.. like cheating...

 

well without seeing all of your code or character setup i can only guess, but if you notice i am using a 'negative' value when calculating ATan2
