Swift Scenekit - Multiple rotations -

i have issue rotating node multiple times. working on game rolling ball, , while can rotate ball along 1 axis, or 2 axis same amount, cannot rotate @ partial angles.

example:

// roll right  90 -  scnnode.pivot = scnmatrix4makerotation(float(m_pi_2), 0, 1, 0)  // roll right 180 -  scnnode.pivot = scnmatrix4makerotation(float(m_pi_2) * 2, 0, 1, 0)  // roll     90 -  scnnode.pivot = scnmatrix4makerotation(float(m_pi_2), 1, 0, 0)  // roll & right 90 -  scnnode.pivot = scnmatrix4makerotation(float(m_pi_2), 1, 1, 0) 

all of work, if need roll ball right 180 , 90 i'm stuck.

even if there way add vectors me.

any appreciated.

to combine effects of rotation matrices, use matrix multiplication.

to in scenekit, can either:

• create separate rotation matrices , multiply them using scnmatrix4mult.
• apply rotation directly existing matrix using scnmatrix4rotate. (this equivalent scnmatrix4makerotation + scnmatrix4mult option; combines steps single function call.)

if order of transformations important app, remember matrix multiplication order reverse of transformation order.
