How do I make an object remains in the frame until it is des

I want the enemies are all stored in the same animation with different frames, it is a game based on tower defense every 1.6 seconds if spawn every enemy, I happen to I configured also if the amount of enemies is greater than ten increasing the wave and every wave when the enemy to be created if it changes its frame, it happens that before dying (when it collides with the target site) it is changing the frame to the other enemy, this because moved wave, does anyone have an idea how can I fix it.

I dont understand what you want.

If you dont want to change frame, just set frame rate to 0.

I want that on every level "wave" is created a new enemy but with the changed frame, it happens that the enemies already in the layout by moving the wave also changes the frame.

Got to pick the one you want.

Now you probaly pick all.
