All,

Anyone know why the following code displays an error but textures the model, whereas if you omit the *scale from the buildModel() no error is shown but the model is not textured?


function setup()
    --
    scale = vec3(0.1,0.1,0.1)
    mod = {
            asset.builtin.Blocky_Characters.Man
            }
    scene = craft.scene()
    -- Setup camera and lighting
    scene.ambientColor = color(61, 61, 61, 255)
    scene.sun:get(craft.light).intensity = 1.0
    scene.sun.rotation = quat.eulerAngles(-45, 125, 0)
    scene.sky.active = false
    viewer = scene.camera:add(OrbitViewer, vec3(0,0,0), 75, 10, 200)
    buildModel()
end

function update(dt)
    --
    scene:update(dt)
end

function draw()
    -- This sets a dark background color
    update(DeltaTime)
    scene:draw()
    collectgarbage()
end

function buildModel()
  --  --
    output.clear()
    ent=scene:entity()
    ent.model = craft.model(mod[1])
    ent.scale = vec3(1,1,1)*scale
    ent.material = craft.material(asset.builtin.Materials.Standard)
    ent.position=vec3(0,0,0)
end

I don’t know why scale causes an error, but the below code works. I change scale to .1 instead of a vec3 and commented out the material line.

function setup()
    --
    scale = .1      --vec3(0.1,0.1,0.1)
    mod = {
    asset.builtin.Blocky_Characters.Man
    }
    scene = craft.scene()
    -- Setup camera and lighting
    scene.ambientColor = color(61, 61, 61, 255)
    scene.sun:get(craft.light).intensity = 1.0
    scene.sun.rotation = quat.eulerAngles(-45, 125, 0)
    scene.sky.active = false
    viewer = scene.camera:add(OrbitViewer, vec3(0,0,0), 75, 10, 200)
    buildModel()
end

function update(dt)
    --
    scene:update(dt)
end

function draw()
    -- This sets a dark background color
    update(DeltaTime)
    scene:draw()
    collectgarbage()
end

function buildModel()
    --  --
    output.clear()
    ent=scene:entity()
    ent.model = craft.model(mod[1])
    ent.scale = vec3(1,1,1)*scale
    --ent.material = craft.material(asset.builtin.Materials.Standard)
    ent.position=vec3(0,0,0)
end

@Bri_G in buildModel the ent.scale is already a vec3, so scale should be just a single number not a vec3.

The model already has multiple materials assigned. when you use ent.material you override those with a single material that does not have any colour assigned.

@dave1707 @piinthesky - thanks for the feedback, I tried scale set at 1 and 0.1 before switching to the vec3() but there were other issues firing up errors. The main problem was the ent.material issue. Thanks for that.

Another problem I have must be related to the viewer setup for the camera. Using the corrected code above it still exists. I use the slider to scale the model but you can pinch and expand to change scale - I get touch errors sometimes when I do that. Have you experienced that?

I’m going to try the other camera option to see if that eliminates it. Thanks again.
