:Acceleration downwards. Value is multiplied by 0.065. When multiple materials are part of the same object, the gravity of that object is based on the proportion that each material makes of that object, factoring in density and size. For example, an object made of paper with 16 grid tiles and steel with 4 grid tiles will have a combined density of 560 (<code>(16×10)+(4×100)=160+400</code>). Paper, with a gravity of 0.3, contributes 0.0<span style="text-decoration:overline;>857142</span> (<code>0.3×(160/560)=0.3×0.<span style="text-decoration:overline;>285714</span></code>) and steel, with a gravity of 1.0, contributes 0.<span style="text-decoration:overline;>714285</span> (<code>1.0×(400/560)=1.0×0.<span style="text-decoration:overline;>714285</span></code>), resulting in a gravity of 0.8. This can be simplified and generalized to the following <code>(a_1×d_1×g_1 + a_2×d_2×g_2 +...+ a_n×d_n×g_n)/(a_1×d_1 + a_2×d_2 +...+ a_n×d_n)</code>, where '''a''' is the area of the material occupies, '''d''' is the material's density, and '''g''' is the material's gravity.
