Debugging in Incari allows the user to follow the path of their Logic's execution. This not only connects Incari Studio with Incari Player in a visual way, but can show all evaluated values as each Node is stepped through.
To enter Debug Simulation, simply locate the icon at the top of the Logic Editor. The image below references this with the green square. It is to the left of the normal Play icon, which would simply start the simulation and open the Player without providing the debugging features.
Once Debug Simulation has been selected, a new toolbar will appear. This is the Debug Toolbar and it has several useful icons which allow the user to maximize their debugging experience in Incari.
The icons from left to right are: Pause/Resume Simulation, Call next node, Step into a function or prefab, Step out of a function or prefab, and Focus on error.
Pause/Resume Simulation allows the user to pause and play the debugging visualization.
Step into a function or prefab can only be used on Function and Prefab Nodes. This lets the user access the Function or Prefab Logic represented by their Nodes in the Scene Logic. The debugging simulation will continue in a separate tab of the Logic Editor and the user can inspect any issues related to Functions or Prefabs.
Step out of a function or prefab exits the Function or Prefab Logic during the debugging simulation and returns to the Scene Logic.
Focus on error highlights the error by navigating to the broken Node and centering it in the Logic Editor's view.
With these features, the user has heightened control over the debugging process.
The user can see the flow of the debugging simulation by following the dot that passes along the connections between Nodes. This can be controlled with the processes maintained by the Debug Toolbar, which are described in the section above.
Breakpoints
The flow can be manually stopped by setting Breakpoints. Simply right-click the Node that the flow of execution should be stopped at (i.e., will not continue into or past this Node), and select Set Breakpoint. This will add a red triangle just before the start of the Node. Alternatively, it can also be removed by doing the same thing once a Breakpoint has been set, and selecting Remove Breakpoint.
Show Values
In Debug Simulation, it is possible to have a Node's values displayed during the flow of execution. Please note that this is not possible outside of Debug Simulation and the values will only appear once that part of the Node has been evaluated. This means that output values will only show once the flow is ready to move onto the next Node.
Example with Stepping into and out of a Function
To better understand the possibilities of the Debug Simulation, an example incorporating a Function is displayed below:
Call next node is very useful. When the simulation has been paused in some way, or stopped by a , the user can use the Call next node to continue through the flow of execution. When a Node has been evaluated completely, a horizontal line will flash brightly beneath its name. When a Node is currently being inspected, a pale horizontal line will be displayed constantly.
