![]() ![]() Literally the only thing they would do is change the default values for the _init_'s arguments. The reason I don't just subclass Tower to create my custom tower types is because they don't really add anything to the class. but they're still individual instances, so it would feel stupid to copy all of these common properties with the same values to every instance separately. So I began with a Tower base class with all the properties I can think of: class Tower(Entity):ĭef _init_(self, image, size, position, attack_speed, attack_damage, attack_splash_radius, attack_range, cost):īut the problem is, all turrets of the same type have same range, same attack speed, same cost, etc. What this means is that I need some kind of generic way to explain how all towers of similar type work, yet I need each instance to be separated. Surface.blit(self.image, self.position, self.size)Īlright so I want my game to work similar to Vector TD, where you have multiple different types of towers that can be build, but you can build multiple instances of each type, and each instance can then be upgraded individually. ![]() So, since both minions and towers have a size and a position, as well as a sprite image, I felt like it'd be appropriate to create a common base class: class Entity:ĭef _init_(self, image, size, position): I'm personally using Python and pygame, but I'm looking for generic design answers that can be applied to any OOP language. The director vector is D= q-p, so if vector x is a position vector, a general vector of the line, is why x-p= t D segment pq is when x= q, so q-p= t (q-p), ie, t=1 and t=0 starting at p so 0 0 so 1-2t=0 t=1/2 Midpoint, P(1,0,1) and Q(4,1-2) ( The other is the same easier ) Director vector D= Q-P = ( 3,1,-3) x- (1,0,1) = (1/2) (3,1,-3) x= (1,0,1) +(3/2,1/2,-3/2) = (5/2,1/2,-1/2) ie Midpoint Xm= (1/2) ( 5,1,-1) We will divide PQ in 3 equal parts ( The same method you can use for midpoint, easier ) First point is such as Ix-pI = (1/3) IDI Ix-pI^2 = (1/9) IDI^2 tD.I'm trying to create a Tower Defense game where minions move through a labyrinth and you can build towers on top of the labyrinths' walls to stop the minions. Consider the vector equation x=p+t(q-p), where p and q correspond to distinct points P and Q in I have no idea how to go about answering this question, can somebody help please. A completely new control scheme that is exclusive to the minis version lets you place/upgrade towers and choose each grid using the D-pad or analog stick. Eight maps (two Beginner, three Normal, and three Extreme) as well as all eleven tower and seven enemy types from the original Flash version are included in Vector TD for PSP. On a grid, Damage and Range Booster towers can be positioned to raise the stats of the towers nearby. You'll also receive a Yellow Energy Cell, which you can spend to buy one of three Boosts, every few waves. Each tower is specifically listed in the in-game manual. Vectoids are slowed down by Blue Ray towers because they consume power. ![]() Heat-seeking rockets are fired at arbitrary targets nearby by the Red Spammer. One Vectoid is targeted by the Green Lasers, for instance, which continue to damage it. Eleven different types of towers are at your disposal, and each one can be upgraded to level 10 (raising the tower's damage and range). ![]() The placement of your towers as well as your choice of upgrade and bonus options will determine your success, in addition to the types of towers you choose. You accomplish this by building turrets alongside the path to combat approaching Vectoids. Players in this installment of the well-known tower defense genre try to get rid of the Vectoid danger before they reach the path's end. ![]()
