Python Package made by Mhadhbi Issam .

DefoldSdk

♠ Install

pip install DefoldSdk

♠ Getting started

♠♠ Example createing new material and assign it to model :

from DefoldSdk import Project


x = Project()
x.new(name = "defoldproject" , path = ".")

modelMaterial= x.newMaterial(name = "pbr" , tags = ['model'])
modelMaterial.setvertex_constant(name='mtx_worldview',typ='Worldview')
modelMaterial.setvertex_constant(name='mtx_view',typ='View')
modelMaterial.setvertex_constant(name='mtx_proj',typ='Projection')
modelMaterial.setvertex_constant(name='mtx_normal',typ='Normal')
modelMaterial.setvertex_constant(name='light',typ='User')
modelMaterial.setfragment_constant(name = 'tint' , typ='User')
modelMaterial.setTexture(name='tex0')
modelMaterial.setvertex_space('local')
modelMaterial.vp = '''
