How do i create breakable blocks?

Hi i wanted to create an 'icy block' which when you stay on it too long it will break apart. Is this possible? and if so, how should i do this?..

As for my understanding, i would need to place a sprite, which when the player is on it, after some seconds it will break apart and he would fall through.

Note: I'm quite new to this program, therefore excuse my ignorance.

Probably easiest way is to check if overlapping the block and every so often increase anim frame to show block cracking or melting. When frame is equal to last frame then destroy block.

-- Sprite Overlapping block

-- System Every 0.25 Seconds --------- > block set block.AnimationFrame+1

------------ block animation frame = 8 ---------- > block Destroy
