Logic Controllers

Logic Controllers are useful when you want to do some complex operations. Here are some list of controllers available in the engine.

• AND Controller
• Or Controller
• NAND Controller
• NOR Controller
• XOR Controller
• XNOR Controller
• Expression Controller
• Python Controller

AND Controller

Controller is activated when every sensor is triggered that is connected to that controller.

Or Controller

Activated when one of the sensor is triggered that is connected to that controller. Yes, any one.

NAND Controller

Activated when every sensor is not triggered that is connected to that controller. Can be used for hover button effect.

NOR Controller

Same as above, activated when every sensor is de-activated.

XOR Controller

Activated when the sensors has mixed input, deactives when every sensor that is connected to the controller is turned on/off.

XNOR Controller

Activated when the sensor has the same input whether it is on/off.

Expression Controller

Can be used for stuff like Conditional Statements in python. Something like this: If the property coins has value equal to or greater than 5, rotate the cube. Here is the project file.

Also you can do stuff like toggling. Here is the project file.

Python Controller

Used for running code, you'll soon learn about this in the comming python lessons. I'll explain the basics: You can either run a full code or a certain part of the code called modules.

Scripts

This is used the run the whole file. The performance can decrease as the module Range or bge is imported again and again in a loop manner. This slows your game performance down. Use it wisely.

Module

Used to run a part of the file called modules. The field must be written like this: your_file.your_module. Your file must have the .py extension or it may return errors.

• Specifies whether it is a module or entire file.
• The name of the file to be loaded.
• Continuously reloads the file.
