Camera rotation with MMB?

Game Engine Game Engine Support and Discussion
1

I just gave BGUI a try a few moments ago and I liked it enough to keep it (obviously :wink: ) but that also means I had to trash my previous mouselook script because the mouse is needed to interact with a GUI. I’ve tried changing it so that the middle-mouse button is what tells it to rotate, without locking the cursor at width/2 height/2 (I do want it to lock… but only in the precise spot that the MMB is clicked on, while its being clicked)

After messing around with it for a bit… It “somewhat” works, but its nowhere near how I’d like it to be. Sometimes the camera starts rotating at extreme angles and won’t stop until the next MMB click, and the cursor doesn’t lock.

Any tips, suggestions? Thanks for your time :slight_smile:

import GameLogic
import game_core
import Rasterizer
import math

controller  = GameLogic.getCurrentController()
obj         = controller.owner

mouse       = controller.sensors["Mouse"]
click       = controller.sensors["mmb"]

rot_LR   = controller.actuators["rotLR"]
rot_UD   = controller.actuators["rotUD"]

rotationLR = [0.0 ,0.0 ,0.0]
rotationUD = [0.0, 0.0, 0.0]
sensitivity = 25
#width = Rasterizer.getWindowWidth()
#height = Rasterizer.getWindowHeight()

def mouseMove():
    x = mouse.position[0]
    y = mouse.position[1]
    if obj['init'] is False:
        obj['x'] = x
        obj['y'] = y
        obj['init'] = True
    return(x, y)

if click.positive:
    move = mouseMove()
    if move[0] > 0.5:       #Fix dumb camera ghosting Left/Right
        rotationLR[2] = (move[0] - obj['x']) * GameLogic.emptyC.rotSpeed / sensitivity
    elif move[0] < 0.5:
        rotationLR[2] = (move[0] - obj['x']) * GameLogic.emptyC.rotSpeed / sensitivity
    
    if move[1] > 0.5:       #Fix dumb camera ghosting Up/Down
        rotationUD[0] = (move[1] - obj['y']) * GameLogic.emptyC.rotSpeed / sensitivity
    elif move[1] < -0.5:
        rotationUD[0] = (move[1] - obj['y']) * GameLogic.emptyC.rotSpeed / sensitivity
    
    rot_LR.useLocalDRot = False
    rot_UD.useLocalDRot = True
    
    rot_LR.dRot = rotationLR
    rot_UD.dRot = rotationUD
    controller.activate(rot_LR)
    controller.activate(rot_UD)
    obj['x'] = move[0]  #Record position for next time
    obj['y'] = move[1]
    Rasterizer.setMousePosition(obj['x'], obj['y'])

Solved my own problem, sorry for the bad post :confused:

    if obj['x'] not in range(move[0]-50, move[0]+50):
        obj['x'] = move[0]
    if obj['y'] not in range(move[1]-50, move[1]+50):
        obj['y'] = move[1]

Hi

It was nice you could share a exemple file.
But sharing the code is good, ill try to implement it

Thanks :wink:
