Ok here are some basic measurements that most people don't know about in level editor.
Please understand that I took some time figuring some of those measurements out.
The highest point for the default player jump height in level editor measurement.
1. Player jump with swords slashes measures about 260 in height.
2. Player jump with no sword slashes measures about 180 in height.
3. Player jump with a gun held measures about 140 in height.
The lengthiest point for the default player jump width in level editor measurement.
1. Player jump length with swords slashes measures about 660 in width.
2. Player jump length with no sword slashes measures about 470 in width.
3. Player jump length with a gun held measures about 330 in width.
The camera measurement for level editor is found in the trigger action 'lock camera in a region' that has a camera parameter of 800x400px.
But since the camera follows the player's cursor we don't get the measurement of the player's camera limitation of how far the player can see.
So I found out that the limitations of the player's cameras are about the parameter of 1600x800px as it is the full limits of the player's camera view based on player's cursor range which is 800x400px multiplied by 2 which gives us the answer 1600x800px as the limits of how far the player's cursor range along with camera scale can go but that is if it's 100% default zoom if not you have to multiply the zoom with the parameters.
