How to Make A Blinking Invincibility Power-Up in GDevelop »

Hey there. I’m ACP_Nate🙂 I’ve been thinking… what if the monsters got stronger when a player reaches level 4 in my game, Truth: Save the Miners!? After some exploration, I discovered how to make a blinking invincibility power-up in GDevelop — something similar to when Mario collects a star… except the bad guys get this boost!

This tutorial will show you exactly how I did it.

👉 How to Make A Blinking Invincibility Power-Up in GDevelop

STEP 1: Create the Trigger or Condition for Your Blinking Invincibility Power-Up in GDevelop

You might want your triggering condition to be a sprite collision, but for my example, I wanted all the monsters to get stronger at level 4. So, I decided to use variables.

I made a global variable called GlobalLevelCounter that increases by 1 every time the player moves to the next level.

Whether you choose sprite collisions (like collectible items), variable triggers (like my level counter), or another setup, you’ll need to establish the condition that starts the power-up action.

STEP 2: Enable the Flash Object Extension

Click the three-lined menu in the upper-left corner of the window. Then, click the “+” symbol near Extensions, and search for Flash Object.

You can use this to make a damaged character temporarily flash, or to signal power-ups like we’re doing in this example.

STEP 3: Add the Behavior to Your Object

After adding the extension, double-click the object that will become powered up. When the object window opens, click the Behaviors tab and add Flash Color Tint.

Now your object is connected to the extension.

STEP 4: Write the Power-Up Logic

Once you’ve set your trigger and added the behavior, it’s time to create an action.

This is where GDevelop’s if/then style of coding shines. My example includes the following conditions:

GlobalLevelCounter ≥ 4
Monsters is on screen
An inverted condition for Monsters is flashing
And most importantly, Trigger Once

On the action side, choose Flash a Color Tint, select the color you want to flash, and set the duration.

In this example, I made the monsters flash for 60 seconds. This prevents the condition from repeating every few seconds and keeps things smooth and optimized.

STEP 5: Define Your Power-Up‘s

Finally… the fun part. Now, you can make your character or enemy move faster, shoot more bullets, drop extra loot, or – as in this example – reduce damage received. You can see in my example that I wanted the damage a blinking/flashing monster received to be reduced to 1, while non-blinking monsters would receive much more damage.
