Script python blender game engine

You can also execute this command from the follwing python script, if you want to create some data first:. You can find more informationon on subprocess here. I would create the objects in a script passed to Blender, as I described above. You can also pass command line arguments to this script if necessary. Any command line argument passed after -- in the command line is treated as an argument for the script. The command line woud change to. I think the easiest way to achieve what you want is to set up the collision detection and player controls in the.

Then you just have to start the game engine's standalone player. Just add these lines to the python script that creates your scene:. To hide the Blender window, start Blender in background mode. Just pass -b as command line argument. The full command should then be:. Notice the -b before the. The standalone player will still be started with a visible window. Sign up to join this community.

The best answers are voted up and rise to the top. Now add a motion actuator too and connect it to the controller. So make your script look like this by adding the bottom four lines:. If nothing was defined within the brackets ex: cont. Now look at the lines for pressup and pressdown. Here we dive into the move actuator. The move actuator is a motion actuator and has different fields we can access and change with python. The dLoc field is actually a list of X,Y and Z values.

If I wanted to get the first value, the X value, I would write it as move. So in short, with this line of code our variable speed will now equal whatever the Y value is at the time the script is run. In brief, this is what we want to happen. Whenever the player presses up, 0. Whenever the player presses down, the Y value is reset to 0, making the car stop. So add in the lines beneath the speed variable so that your script looks like this:.

This if statement is used to detect whether or not the up button has been pressed. Your if statement needs a colon at the end of it, and any action part of this statement needs to be tabbed in beneath it. Now if the player presses up, 0. If you want to change other fields in the actuator, to figure out what options are available you can use print dir move. So now we simply plug the speed variable in as the Y value in the list there and it will change the value in the actuator.

To make this actuator active now, we use the line cont. Now our car moves faster. So add in the lines at the bottom so your script looks like this:.

So if the player is pressing down instead of up, we set the speed value to 0, deactivate the move actuator which stops the car, and finally we reset the Y value in the dLoc field back to 0. Your script is complete! Start the game! Now press up repeatedly to gain speed, and press the down key to stop. There may be errors in your script that prevent if from running properly.

How exactly, in Python, can someone get if an object is colliding? I remember reading at some point about bullet physics debug Python in Blender, would it be possible to do something with that?

Any help is appreciated, thanks.
