Minecraft mid-command delay for 1.15.2

minecraft-commandsminecraft-java-edition

How do you put a delay in the middle of command?

I'm making a TNT run (without TNT) and my issue is, when you start TNT run and you start jumping, sometimes a command block will register the block under you and delete it, and sometimes it will happen even before you will jump again, so you will fall to another layer/void instantly without making a mistake.
Here is the command that I'm using:

/execute as @a[distance=..100] at @a[distance=..100] if block ~ ~-0.5 ~ cyan_terracotta run setblock ~ ~-0.5 ~ air

(command block is "unconditional" and mode is "repeat (purple)")

All I want is just a delay; for example, half a second between "command block realised there is cyan_terracotta under player" and "setting block air under player" to let the player jump before falling down the layer.

You can't do it in one command, as far as I know. However, you can use a scoreboard objective to count the ticks that a player has been on cyan_terracotta for.

First create a dummy scoreboard objective: (I've called it obj here)

/scoreboard objectives add obj dummy

Then reset scores for players who aren't standing on cyan terracotta:

/execute as @a at @s unless block ~ ~-1 ~ cyan_terracotta run scoreboard players reset @s obj

Now increment the score for players who are on cyan terracotta:

/execute as @a at @s if block ~ ~-1 ~ cyan_terracotta run scoreboard players add @s obj 1

Then run your command at each player when it has been half a second:

0.5 seconds * 20 ticks per second
10 ticks
/execute as @a at @s if score @s obj matches 10.. run setblock ~ ~-1 ~ air
