Character Control

+

+ We will make character physics controller which is + KX_CharacterWrapper type. + This allows us to check if the character has landed, + control number of jumps it can do, etc. +

+

Setup

+

+ Select the cube, change it's physics type to Character, drag it up on the + Z axis to around 3-4.
+

+

Logic Bricks

+

+ To setup the logic bricks, we need to know how the player will + be controller. My guess is something like this. +

+
+ logic bricks setup +
Logic Bricks Setup
+
+

+ The keyboard keys will be controlled with python. +

+

Coding

+

+ Import the game engine module, define our python controller and owner. +

+ 
try:
+    import Range
+except:
+    import bge as Range
+
+cont = Range.logic.getCurrentController()
+own = cont.owner
+
+def move():
+    pass
+

+ The move function will run in a loop. + Next we need to move our character when the keyboard sensors is triggered. +

+ 
def move():
+    keyboard = cont.sensors["Keyboard"] # Get sensor as "keyboard"
+    y = 0 # Forward / Backward
+    z = 0 # Turn
+    jump = (0,0,0) # Jump Direction
+    if keyboard.positive: # If keyboard is triggered
+        if 45 in keyboard.inputs: # W key
+            y = 1/8
+        if 23 in keyboard.inputs: # A key
+            z = 1/8
+        if 41 in keyboard.inputs: # S key
+            y = -1/8
+        if 26 in keyboard.inputs: # D key
+            z = -1/8
+        if 8 in keyboard.inputs:  # SPACE key
+            pass # Do nothing, will be implemented later
+        else: # Reset everything
+        	x = 0
+        	z = 0
+        	jump = 0
+

+ Here, we've setup the movement when the keyboard is pressed. + Now we need to get the character ID. +

+
+

+

+ Getting the character ID is mandatory or the character you control becomes + KX_GameObject. +

+
+ 
player = Range.constraints.getCharacter(own)
+

+ We got our character ID, now we need to implement the player movement. +

+ 
def move():
+    keyboard = cont.sensors["Keyboard"]
+    y = 0
+    z = 0
+    jump = (0,0,0)
+    if keyboard.positive:
+        if 45 in keyboard.inputs:
+            y = 1/8
+        if 23 in keyboard.inputs:
+            z = 1/8
+        if 41 in keyboard.inputs:
+            y = -1/8
+        if 26 in keyboard.inputs:
+            z = -1/8
+        if 8 in keyboard.inputs:
+            player.jump() # The proper jump
+    else:
+        x = 0
+        z = 0
+        jump = 0
+                    
+    player.walkDirection = (0,y,0) # Movement but in world coordinates
+    own.applyRotation((0,0,z), True) # Turn left and right
+

+ If you run the script, the character moves in world coordinates, + to solve this we multiply worldOrientation + that returns us Matrix with the tuple (0,y,0) + which will be converted into a Vector with mathutils module. +

+ 
player.walkDirection = own.worldOrientation * Vector((0,y,0))
+

+ And we create a property that returns us the + KX_CharacterWrapper.onGround as True or False. +

+ 
own["landed"] = player.onGround
+

+ And the final code looks like this. +

+ 
try:
+    import Range
+except:
+    import bge as Range
+
+from mathutils import Vector
+    
+cont = Range.logic.getCurrentController()
+own = cont.owner
+player = Range.constraints.getCharacter(own)
+
+def move():
+    keyboard = cont.sensors["Keyboard"]
+    y = 0
+    z = 0
+    jump = (0,0,0)
+    if keyboard.positive:
+        if 45 in keyboard.inputs:
+            y = 1/8
+        if 23 in keyboard.inputs:
+            z = 1/8
+        if 41 in keyboard.inputs:
+            y = -1/8
+        if 26 in keyboard.inputs:
+            z = -1/8
+        if 8 in keyboard.inputs:
+            player.jump()
+    else:
+        x = 0
+        z = 0
+        jump = 0
+                    
+    player.walkDirection = own.worldOrientation * Vector((0,y,0))
+    own.applyRotation((0,0,z), True)
+    own["landed"] = player.onGround
