Help with Changing images based on the level

Method one
Animation frames

Pros:
- Best option for single frame animations

Cons:
- Only useable with single frame animationsPreparation:Use only one animation and add the different level frames to the animation.

Events:
Start of frame: Force animation frame

If all levels have unique graphics, you can use a calculation to set the animation frame, else you need to set up events to select which animation frame to force the active object to display.

Method two
Animations

Pros:
- Good for multi-frame animations
- Need only one event

Cons:
- Takes longer time to set up
- Takes up much memory when there are many levels
- Might need several eventsPreparation:
Create a new animation for each level

Events:
Start of frame: Set animation

If all levels have unique graphics, you can use a calculation to set the animation, else you need to set up events to select which animation for the active object to play

Method three
Qualifiers

Pros:
- Good when levels are loaded from a file
- Takes up little memory
- Needs only one event

Cons:
- Takes the longest time to set up
- Fills up the workspace with objects (you might want to group them)
- Needs a level editor or dummy objects

Preparation:
Create a new active object for each animation
Give all objects the same qualifier
Objects should not be created from start
If you don't intend to create a leveleditor, place dummy objects that will be replaced by events according to the level

Events:
Start of frame: Create object by name

You can have an ini file that has the names of the objects for each level, or simply name the objects according to their level number like Object A Level 1, Object A Level 2 etc...
If done right, you should be able to pull this off using only one event.
