Grand Touring

Post by SWEET_TOOTH »

Basically working on a gran turismo 2D clone. For now making acceleration and driving mechanics. I have some experience with gamemaker 8 and 6 years of experience with gamemaker:studio. I still struggle a lot with this. Would like to see more documentation or code in action... Anyway, the plan is to get player and some AI cars to race in circuits. There is an example with saving and loading which is great, but I hope It works the same way on 5.12 version. Maybe someone could help me figure out how to use PA_Sin and PA_Cos functions on Float variables?



VERSION: alpha testing phase

Well, they are working, only 1 sprite and 1 background (edited with that blue color) to match 256x256 image dimmentions. Otherwise I get graphical errors. So far everything works as it should.

If you haven't already, you can check out the DSGM 5.12 post dicussing Cos and Sin function. I have an example of using them posted in that topic that you can download.

Yeah I got it done using precise float variables because I really needed it tp be accurate... Anyway I would rly need a tool to calculate how much DS ram is used... I dont want to rewrite half oc code bcs of it missing

Wish I knew of a way to find that out. I typically just playtest my game until I get the below message stating I ran out of Vram and then I adjust my game to use fewer room objects or less intensive code.

It's not an ideal workflow, but here are some performance restrictions to know that might apply to your game.

Notable DSGM 5.12 Performance Restrictions
  • An array only applies for the first 128 game objects in a room. (If you have more than 128 objects expect glitches)
  • If you're using rotation, only 32 objects can exist in a room without problems.
  • Game objects can often cause graphical glitches if they are deleted while animating or while collided with another game object.
  • Swapping an object's sprite is more process intensive than switching its frame (I learned that by accident by crashing my game when 3 objects changed sprites at the same time)
  • 1024x768 is the largest room size that still allows for a functional collision map

These are really good advices, but damn... It's restrictive as hell. I really need to find a way to have bigger maps with collision. For now my game has like 30 objects and a very very big map like 4000x3000 pixels and still runs fine 60fps even after collisions... Let's talk someday so we both can take a peek into it.
