examples: Sugerscape_g1mt is missing input Model Params (Sliders etc.)

[EwoutH]

The Sugerscape_g1mt app.py is missing any input Model Params (like Sliders etc.) to play with in the visualisation.

mesa/mesa/examples/advanced/sugarscape_g1mt/app.py

Lines 49 to 52 in a04e20b

	model_params = {
	"width": 50,
	"height": 50,
	}

I tried to add these:

model_params = {
    # Grid parameters
    "width": Slider("Grid Width", value=50, min=20, max=100, step=10),
    "height": Slider("Grid Height", value=50, min=20, max=100, step=10),

    # Population parameters
    "initial_population": Slider("Initial Population", value=200, min=50, max=500, step=10),

    # Agent endowment parameters
    "endowment_min": Slider("Min Initial Endowment", value=25, min=5, max=30, step=1),
    "endowment_max": Slider("Max Initial Endowment", value=50, min=30, max=100, step=1),

    # Metabolism parameters
    "metabolism_min": Slider("Min Metabolism", value=1, min=1, max=3, step=1),
    "metabolism_max": Slider("Max Metabolism", value=5, min=3, max=8, step=1),

    # Vision parameters
    "vision_min": Slider("Min Vision", value=1, min=1, max=3, step=1),
    "vision_max": Slider("Max Vision", value=5, min=3, max=8, step=1),

    # Trade parameter
    "enable_trade": {"type": "Checkbox", "value": True, "label": "Enable Trading"},
}

But modifying things lead to all kinds of error and unexpected behavior. For example, changing the width only did so partially (and apparently the height instead of the width):

I suspect that's due to the model first being initialized (with model1 = SugarscapeG1mt()), and then the slider value being modified.

I don't see a problem with SolaraViz here. Changing "initial population" seems to work just fine. Disabling trade removes "price" from the line chart, which I assume is intended. The other parameters are hard for me to judge, since I don't know how they impact the model.

Width and Height are indeed broken, but this seems to be implementation specific. The underlying "sugar-map.txt" just seems to be a 50x50 matrix. So I guess no wonder it doesn't work if you set it to larger values. Smaller seems to be fine, except the swapping of height and width.
