Thoughts:
Relatively new to game jams or low staff/time:. 1 boss 1 biome 2-3 enemies 2 upgrades If you’re stuck with how to start on level design for a Metroidvania, start by going small. A good place to start is with a 3x3 room layout.
you’re going to need to make at least 1 tileset, and a set of player animations, and animations for enemies and power ups
if you’re building melee animations for the main character, animating them on a grid that’s three times larger than the base character helps give plenty of room for bigger hitboxes and expressive animations. If your game’s tiles are on 16x16, you’d animate your character on 48x48.
You shouldn’t build difficulty from tedium. There are many ways to add challenge into a Metroidvania, but damage sponges are boring. There is an element of taste here, but if you’re spending multiple moments at a time doing nothing but pressing a button to do damage, without having to dodge or otherwise make a reaction or decision, the enemy is probably too tanky. The same goes for super long platforming segments with death pits and few checkpoints. There can be ways to make it thematically appropriate, but this is one of those things you want to learn to do right, before you break it. Highly punishing platforming segments (or the same in other genres) also get tedious after a while. Variety helps make a pleasant experience. A good question to consider is “can I get this level design idea across in fewer ‘screen’s of map than what I’m currently using?” The more screens you have, the more you’ll need to find ways to mix things up, the fewer screens, the more your existing variety spices things up.

Physics
Vectors are quantities that are fully described by both a magnitude and a direction.
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
• Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name. It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. A matter of fact, this quantity known as the acceleration of gravity is such an important quantity that physicists have a special symbol to denote it - the symbol g.
The book in motion on the table top does not come to a rest position because of the absence of a force; rather it is the presence of a force - that force being the force of friction - that brings the book to a rest position. In the absence of a force of friction, the book would continue in motion with the same speed and direction - forever!
Inertia is the tendency of an object to resist changes in its state of motion. But what is meant by the phrase state of motion? The state of motion of an object is defined by its velocity - the speed with a direction. Thus, inertia could be redefined as follows:
Inertia: tendency of an object to resist changes in its velocity.
Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has.
Equilibrium:
There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.
Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.
Unbalanced Force:
Yet there is no force present to balance the force of friction. As the book moves to the right, friction acts to the left to slow the book down. There is an unbalanced force; and as such, the book changes its state of motion. The book is not at equilibrium and subsequently accelerates. Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down.
Force:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
Contact Forces Frictional Force Tension Force Normal Force Air Resistance Force
Applied Force
Spring Force
Action-at-a-Distance Forces Gravitational Force Electrical Force Magnetic Force
Newton:
Force is a quantity that is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N." To say "10.0 N" means 10.0 Newton of force. One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. Thus, the following unit equivalency can be stated:
1 Newton = 1 kg • m/s2
A force is a vector quantity. a vector quantity is a quantity that has both magnitude and direction. To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the directio
because forces are vectors, the effect of an individual force upon an object is often canceled by the effect of another force. For example, the effect of a 20-Newton upward force acting upon a book is canceled by the effect of a 20-Newton downward force acting upon the book. In such instances, it is said that the two individual forces balance each other; there would be no unbalanced force acting upon the book.
Type of Force(and Symbol) | Description of Force |
Applied Force
Fapp | An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.Return to Top |
Gravity Force
(also known as Weight)
Fgrav | The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found by the equation:Fgrav = m * gwhere g = 9.8 N/kg (on Earth)
and m = mass (in kg)
(Caution: do not confuse weight with mass.)
Return to Top |
Normal Force
Fnorm | The normal force is the support force exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book. On occasions, a normal force is exerted horizontally between two objects that are in contact with each other. For instance, if a person leans against a wall, the wall pushes horizontally on the person.Return to Top |
Friction Force
Ffrict | The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion. Friction results from the two surfaces being pressed together closely, causing intermolecular attractive forces between molecules of different surfaces. As such, friction depends upon the nature of the two surfaces and upon the degree to which they are pressed together. The maximum amount of friction force that a surface can exert upon an object can be calculated using the formula below:Ffrict = µ • Fnorm
The friction force is discussed in more detail later on this page.Return to Top |
Air Resistance Force
Fair | The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object. This force will frequently be neglected due to its negligible magnitude (and due to the fact that it is mathematically difficult to predict its value). It is most noticeable for objects that travel at high speeds (e.g., a skydiver or a downhill skier) or for objects with large surface areas. Air resistance will be discussed in more detail in Lesson 3.Return to Top |
Tension Force
Ftens | The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.Return to Top |
Spring Force
Fspring | The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it. An object that compresses or stretches a spring is always acted upon by a force that restores the object to its rest or equilibrium position. For most springs (specifically, for those that are said to obey "Hooke's Law"), the magnitude of the force is directly proportional to the amount of stretch or compression of the spring.Return to Top |
a doubling of the net force results in a doubling of the acceleration (if mass is held constant).
a halving of the net force results in a halving of the acceleration (if mass is held constant).
Acceleration is directly proportional to net force.
Acceleration is inversely proportional to mass.
