The trick is to create a function with the title delaySpawn first.
Next, you'll add three parameters to the function. (for more practice with this, check out the skills and drills vox-l < learning to program < parameters lessons) Click the blue star on the function block. A pop up menu will then appear. Click and drag three input blocks into the popup. Then into the input blocks the parameters: ent num timeout init name. Then, click the blue star again to exit the popup.
Then look in the functions tab on the Blockly menu.
