So I am, again, stuck with the problem of interacting via collision entries. I’ve managed to access the actor from the entries, but I am now unable to acces the methods of the actor’s class. My basic setup is that I have a Moving() task-method and a Move() method within the Unit() class, and I want to, from within my World() class, trigger the Move() method in response to a right mouse-click, which activates the Moving() task.
The trouble is, I get “libpanda.NodePath has no attribute ‘moving’” when I try to call the Unit() class’s Moving() function via an instance of Unit() called ‘unit’. I have also tried adding the task to the taskmanager directly from the World() class, which was unsuccessful.
I thought that the way to call a class’ methods from within another class was to use an instance, and I believe that’s what I’m doing, so what’s the problem?
Here is the relevant code. First, the click-triggering:
def rightClick(self):
for i in range(self.moverHandler.getNumEntries()):
entry = self.moverHandler.getEntry(i)
if (entry.getIntoNode().getName() == "floorcollider"):
for oldArrow in self.indicatorArrow:
oldArrow.remove()
self.indicatorArrow = []
pos = entry.getSurfacePoint(render)
arrow = indicatorArrow(pos)
self.indicatorArrow.append(arrow)
for unit in self.selectedUnits:
position = unit.getPos(unit)
target = entry.getSurfacePoint(unit)
moveVector = target - position
moveHeading = math.degrees(math.atan2(moveVector.getY(), moveVector.getX())) + 90
if moveHeading < 0:
moveHeading += 360
unit.setH(unit, moveHeading)
unit.move(pos)Then, the unit’s movement code:
def move(self, pos):
taskMgr.add(self.moving, "moving", extraArgs=[pos])
def moving(self, task, target):
self.pos = self.actor.getPos(self.actor)
self.targetPos = target.getPos(self.actor)
self.move = self.targetPos - self.pos
self.moveX = self.move.getX()
self.moveY = self.move.getY()
self.moveZ = self.move.getZ()
self.twoDdistance = math.sqrt((self.moveX * self.moveX) + (self.moveY * self.moveY))
self.threeDdistance = math.sqrt((self.twoDdistance * self.twoDdistance) + (self.moveZ * self.moveZ))
if self.threeDdistance > 5:
self.actor.setY(self.actor, +40 * globalClock.getDt())
return task.cont
elif self.threeDdistance <= 5:
return task.doneKeep in mind that I am trying to make the code viable even if several units are moving at once, RTS-style, which one reason it seems a better idea to have the movement handled in the unit class itself, rather than in a superordinate class.
Any and all help is greatly appreciated!
