Kind soul needed to help with Mouse Up and Mouse Down

[cdutoit]

I love playmaker and the tutorials helped a lot. Where I really struggle is when trying to use the input events.

I'm trying to port to Playmaker a "flight control" game - where you select a plane and then draw a flight path for the plane to follow.

I don't want to use Mouse Drag since that will be hard to port to touch. The existing code for the game that I'm trying to port (C#) makes this very easy:

Code: [Select]

void Update ()
{

//if we are controlling the plane and the game is not over
if (controlPlane && !player.gameover)
{

//if mouse button is up
if (Input.GetMouseButtonUp(0))
{
//set controlPlane to false
controlPlane = false;
}

//get mouse position
inputPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
// do stuff

}


}

//if click or touch the plane
void OnMouseDown()
{

    // Do some stuff...details not important

//set controlPlane to true
        controlPlane = true;


}
    }



Very simply, in the mouse down function they set a boolean to true.

Then, in the update function they simply look for this boolean to be true and if it is, simply grab the current mouse position.

In playmaker, I can create a state with a global transition for MOUSE DOWN and set the boolean to true.

But then I'm lost...where would I put the corresponding code of the update function?

I've tried all different kinds of things and can't crack which should be a simple port. I'd be happy to hear any and all suggestions  - or even otherwise of implementing a "click and draw" implementation in Playmaker.

After 4 days of struggling I figure it's time to turn to the experts!

Thanks in advance

You don't really need to maintain the bool anymore if you're porting this to Playmaker. You can just use Mouse Down to make a direct transition to another state where you do your Screen To World Point and include a Mouse Up action that fires an event back to the previous state.

Thanks, Lane.

I'm making progress, albeit slowly. Sometimes its easier to code it than to use Playmaker but I'm determined to get this modeled as FSM's.
